Answer:x = -4
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x+6-3*(x-2)-(x+4)=0
Step by step solution :

:
Equation at the end of step 1
((6x + 6) - 3 • (x - 2)) - (x + 4) = 0

Pulling out like terms
3.1 Pull out like factors :
2x + 8 = 2 • (x + 4)
Equation at the end of step

:
2 • (x + 4) = 0

:
Equations which are never true:
4.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x+4 = 0
Subtract 4 from both sides of the equation :
x = -4
First expand the brackets -3(x-2) =-3x+6
Rewrite the equation: 6x+6-3x+6=x+4
Simplify where possible:3x+12=x+4
Solve: whatever you do on one side do it on the other
-x 3x+12=x+4 -x
2x+12=4
-12 2x =4 -12
2x=-8
