Question

Solve for r in the equation 7 + (r / -2) = 3.

A. r = -28
B. r = 14
C. r = -14
D. r = 28

Answer 1

The correct solution to the equation 7 + (r / -2) = 3 is r = 8, which is not listed in the provided options. There seems to be an error as none of the options (A. -28, B. 14, C. -14, D. 28) match the correct answer.

Step-by-step explanation:

To solve for r in the equation 7 + (r / -2) = 3, follow these steps:

1. Subtract 7 from both sides of the equation to get (r / -2) = 3 - 7, which simplifies to (r / -2) = -4.
2. Multiply both sides of the equation by -2 to isolate r. Doing so, we get r = -4 * -2.
3. Therefore, r = 8, which is not one of the options provided.

It appears there might be an error in the question or the options given, as the correct answer, r = 8, is not listed among the choices A through D.
