Answer:
To make x the subject of the formula, we can isolate x by subtracting 1 from both sides of the equation:
x + 1 = 4y
x + 1 - 1 = 4y - 1
x = 4y - 1
So x is equal to 4y minus 1.
Explanation:
Currently x is on the left side of the equal sign and is being added to 1. x has to be isolated and be by itself on one side of the equal sign in order to be made the subject of the formula. Therefore the 1 needs to be moved to the other side of the equal sign:
