This week in math I learned what substitution for linear equations were. Substitution as you may already know is when you take something out and replace it with something else. In math we did that with equations. First we start off with 2 equations and choose which one to rearrange so either x or y equals to something. Then input the rearranged equation into one of the other equations’ variables in brackets then solve. Once you’ve found the answer, input that into the rearranged equation and you should get the other variable’s answer. Once completed verify the solution.
