Answer:x=10
Step-by-step explanation:
1. Simplify both sides of the equation. -3(x+4)=-6x+18 to -3x - 12=-6x + 18
2. Add 6x to both sides. -3x - 12=-6x + 18 to -3x - 12 + 6x=-6x + 18 +6x which would equal to 3x - 12=18
3. Add 12 to both sides. 3x - 12 + 12=18 + 12.
4. Divide both sides by 3. 3x/3=30/3 which equals x=10.
