Solving using substitution
There are also many YouTube videos that can show you how to Solve using substitution. A binomial solver is a math tool that helps solve equations with two terms. This type of equation is also known as a quadratic equation. The solver will usually ask for the coefficients of the equation, which are the numbers in front of the x terms. It will also ask for the constants, which are the numbers not attached to an x. With this information, the solver can find the roots, or solutions, to the equation. The roots tell where the line intersects the x-axis on a graph. There are two roots because there are two values of x that make the equation true. To find these roots, the solver will use one of several methods, such as factoring or completing the square. Each method has its own set of steps, but all require some algebraic manipulation. The binomial solver can help take care of these steps so that you can focus on understanding the concept behind solving quadratic equations.
Negative exponents in fractions can be solved by using the reciprocal property. This states that when taking the reciprocal of a number, the exponent becomes the opposite sign. So, to solve a fraction with a negative exponent, you simply take the reciprocal of the base number and then change the sign of the exponent.
How to solve using substitution is best explained with an example. Let's say you have the equation 4x + 2y = 12. To solve this equation using substitution, you would first need to isolate one of the variables. In this case, let's isolate y by subtracting 4x from both sides of the equation. This gives us: y = (1/2)(12 - 4x). Now that we have isolated y, we can substitute it back into the original equation in place of y. This gives us: 4x + 2((1/2)(12 - 4x)) = 12. We can now solve for x by multiplying both sides of the equation by 2 and then simplifying. This gives us: 8x + 12 - 8x = 24, which simplifies to: 12 = 24, and therefore x = 2. Finally, we can substitute x = 2 back into our original equation to solve for y. This gives us: 4(2) + 2y = 12, which simplifies to 8 + 2y = 12 and therefore y = 2. So the solution to the equation 4x + 2y = 12 is x = 2 and y = 2.
There are a few things you can do to help with math word problems. First, read the problem carefully and try to understand what it is asking. Next, identify any key words or concepts that you need to solve the problem. Then, work through the problem systematically, using either pencil and paper or a calculator. If you get stuck, try to break the problem down into smaller pieces or ask a friend or teacher for help.

This really helped me out when I was stuck on a task. I would highly recommend to download and try it out for your self’s. It might be a tiny bit hard to follow up on the solutions but if you have the basics to the task, you need help on, it will be a breeze to understand!
Very helpful and clearly-understandable steps I like playing with math, and used to be pretty good at it, but if you don't practice, you forget. Now that my kids are in Middle and High School, this app lets me help them by reminding me of principles and theorems. The app is efficient, easy to use, and makes good use of the device's camera for input with minimal errors.
