Question

Compute a value for y that satisfies the equation below.





–3y – 12 = –4

Answer 1

To do that we have to first solve for y...

-3y -12 = -4
Add 12 to both sides...

-3y = 8
divide by -3 on both sides to isolate y...

y = -8/3

Check to see if it satisfies the equation by plugging (-8/3) for y in the original equation...

-3(-8/3) - 12 = -4

8 - 12 = -4

-4 = -4 True

It checks so the solution set is {-8/3}
