Answer:
x = 2
Step-by-step explanation:
The left side would be (3x - 12)
The right side would be (-4x+2)
In an equation, 3x - 12 = -4x+2
Combine all the letters on the left and plain numbers on the right,
3x + 4x = 12 + 2
Note: When you transfer to the other side of the equal sign, the number will change its sign.
Simplify the 3x + 4x = 12 + 2,
7x = 14
x = 2
