If -2(3y+5)=-4, find the value of 5y.

Answer 1

divide by -2 to get 3y+5=2

subtract 5 to get 3y =-3

divide by 3 to get y=-1

check the answer

-2(-1(3)+5)=-4

-2(-3+5)=-4

-2(2)=-4

-4=-4 that tells us we got the correct value for y=-1

but you want 5y, that's 5(-1)=-5

Answer 2

If -2(3y+5)=-4, find the value of 5y.

First, expand and simplify the equation:

-2(3y + 5) = -4

-6y - 10 = -4

-6y = 6

y = -1

5y = -5
