Question

Show the steps to get full credit 3 (2x + 2) = 18 + 4(x - 5)

Answer 1

Answer:

$x=-4$

Step-by-step explanation:

So we have the equation:

$3(2x+2)=18+4(x-5)$

Distribute the left and the right:

$3(2x)+3(2)=18+4(x)+4(-5)$

Simplify:

$6x+6=18+4x-20$

Combine on the right:

$6x+6=4x-2$

Subtract 4x from both sides. The right cancels:  

$(6x+6)-4x=(4x-2)-4x\\2x+6=-2$

Subtract 6 from both sides. The left cancels:

$(2x+6)-6=(-2)-6\\2x=-8$

Divide both sides by 2:

$(2x)/2=(-8)/2\\x=-4$

Thus, the value of x is -4.

Answer 2

Answer:

x = -4

Step-by-step explanation:

3(2x + 2)=18 + 4(x - 5)

6x + 6= 18 +4x - 20

6x - 4x = -2-6

2x = -8

x = -4
