Question

Solve -3(x+4) = 7x + 4 all steps

Answer 1

Answer:

-8/5 = x

Step-by-step explanation:

-3(x+4) = 7x + 4

Distribute

-3x-12 = 7x+4

Add 3x to each side

-3x-12+3x = 7x+4+3x

-12 = 10x+4

Subtract 4 from each side

-12-4 = 10x+4-4

-16 = 10x

Divide by 10

-16/10 = 10x/10

-8/5 = x

Answer 2

Answer:

x = $\frac{-8}{5}$ or x = -1.6

Step-by-step explanation:

-3(x+4) = 7x + 4

do the left side first

multiply x by -3 and multiply 4 by -3

you get -3x - 12 = 7x + 4

add 3x to both sides

you now have -12 = 10x + 4

subtract 4 from both sides

you get -16 = 10x

divide each side by 10

you have x = $\frac{-8}{5}$ or x = -1.6
