Which of the following is a valid solution to the equation 3(x + 4) = 2(x - 1)?a.x = -10b.x = -12c.x = -14d.x = -16
Question
Solution
To solve the equation 3(x + 4) = 2(x - 1), follow these steps:
Step 1: Distribute the 3 and the 2 on the left and right sides of the equation respectively. This gives us 3x + 12 = 2x - 2.
Step 2: Subtract 2x from both sides to get x + 12 = -2.
Step 3: Subtract 12 from both sides to solve for x. This gives us x = -14.
So, the correct answer is c. x = -14.
