To solve x+y=4 for y, we need to move the x to the right side of the equation so the yy will be isolated. Since x is being added to the y, we need to subtract x on both sides because subtraction is the inverse operation of addition. Subtracting xx on both sides then gives:

x+y=4 \ Given equation. x+y−x=4−x \ Subtract x on both sides.x+y y=4-x \ Simplify.

Therefore, x+y=4 solved for y is y=4−x

x+y=4 \ Given equation. x+y−x=4−x \ Subtract x on both sides.x+y y=4-x \ Simplify.

Therefore, x+y=4 solved for y is y=4−x
