Solve each equation for y.

x+y=9

Short Answer

Expert verified

The required solution is y=9-x.

Step by step solution

01

– State the concept

An equation solved for y gives an equation where y is the only thing on the left-hand side and the other terms are on the right-hand side.

02

– List the given data

The given equation is x+y=9.

03

– Solve for y 

x+y=9 (Given equation)

x+y-x=9-x (Subtract x from both sides)

y=9-x (Simplify)

So, the required solution is y=9-x.
