Question

The solution shown for the equation is incorrect. What is the error?

a.-2(3-m)=12
b-6-2m=12
c-2m=18
d.m=-9

Answer 1

The error in the given equation is in option c, -2m = 18. To find the error, divide both sides of the equation by -2 to isolate m. The correct solution to the equation is d. m = -9.

Step-by-step explanation:

The error in the given equation is in option c, -2m = 18.

To find the error, we can solve the equation step by step:

1. Start with the equation: -2m = 18
2. Divide both sides of the equation by -2 to isolate m: (−2m)/(-2) = 18/(-2)
3. When we divide both sides by a negative number, the inequality sign flips. So, the equation becomes: m = -9

Therefore, the correct solution to the equation is d. m = -9.
