Solve the equation.

3(2x+5)=-6=9

What does x equal?

x = -2

Step-by-step explanation:

Expand:

6x + 15 = -6 + 9

6x + 15 = 3

Put 15 on the other side

6x + 15 - 15 = 3 - 15

6x = -12

x = -2

-2

Step-by-step explanation:

3(2x+5) =-6 +9

6x +15 =3

6x=3 - 15

6x =-12

x=-12:6

x=-2

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
