How do i solve y/9=-2

Question

I'm trying to help my son with 7th grade math

Answer 1

If y/9=-2 and we want to solve for y then we need to multiply both sides of the equation by 9.

 

y*9/9=-2*9 we know that 9/9 = 1

y then = -2*9 or y= -18

 

Hope that helps

Answer 2

the idea on an expression like this is that you're trying to isolate the variable by itself. for this one you can do that by multiplying both sides by 9

y/9 = -2

y = -2 * 9

y = -18
