How to solve a two step algebra equation:

Step 1: Add or subtract the number that isn’t connected to a variable.

Ex 1: 5x+20=40; the highlighted part is what you would subtract. Because of the addition sign, you need to subtract. If there was a subtraction sign, you would add because you just need to cancel it out. This is what happens: solve 2 step equation

Step 2: Divide the coefficient. You need to isolate the variable. The goal is to get the 5 on the other side.

Ex 2: 5x=60; the highlighted part is what you need to divide by five. If it was division, you would need to multiply by five. You just have to do the inverse operation.

Step 3: What you do to one side, you need to do to the other side.

Ex 3: 60 divided by 5.

That’s how you do it!!
