Question

How to solve y in -(y+9)=10

Answer 1

Answer:

Step-by-step explanation:

- (y+9) = 10

Multiply through by -1 gives us

y+9 = -10

Subtract 9 from both sides

y = -19

That's your answer.

If you work it through it satisfies the equation.

That is:

- (-19 +9) = 10

-(-10) = 10

10 = 10

Boo ya!
