How do you solve for y given #x+y=9#?

Answer 1

Abigail Allen

See the entire solution process below:

Subtract #color(red)(x)# from each side of the equation to solve for #y# while keeping the equation balanced:

#-color(red)(x) + x + y = -color(red)(x) + 9#

#0 + y = -x + 9#

#y = -x + 9#

To solve for ( y ) given ( x + y = 9 ), you can subtract ( x ) from both sides of the equation. The resulting equation will be ( y = 9 - x ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
