Question

I need to know how to do this fast

Answer 1

Photo math works, but just saying two step equations are pretty fun! The goal is to get the variable (x) by itself; alone on one side of the equal sign. I’m going to explain #1. 7x has to be by itself, so you will move the +9 over to the other side of the equal sign. When you move a number/thing over the equal sign, it turns negative (negative turns to positive, positive turns to negative). So, it will become 7x = 58 -9. You will do simple subtraction to get 7x = 49. Divide each side by 7 to get x by itself, and you have x = 7!
