Solve: -6(x + 3) = 24.
Ax=7
Bx=-7
Cx=-3
Dx=1
Answer & Solution
Correct answer: B. x=-7
1. Distribute on the left: -6(x + 3) becomes -6x - 18.
2. The equation is now -6x - 18 = 24.
3. Add 18 to both sides: -6x equals 42.
4. Divide both sides by -6 to get x equals -7, and checking confirms -6(-7 + 3) equals -6(-4) equals 24.
