15 = 5 - 2 x
2(15) - 5 = x
15 - 5 = 2 x **Weegy:** Sarah's age is five less than twice her sister's age. Sarah is fifteen years old. 2x - 5 = 15 could be used to solve for the age of Sarah's sister. **User:** Solve x/-4 - (-8) = 12.

To solve the equation x/2 - 3 = 7, we will isolate the variable x by performing the necessary operations.

First, we'll add 3 to both sides of the equation:

x/2 - 3 + 3 = 7 + 3

This simplifies to:

x/2 = 10

Next, we'll multiply both sides of the equation by 2 to eliminate the fraction:

2 * (x/2) = 2 * 10

This gives us:

x = 20

Therefore, the solution to the equation x/2 - 3 = 7 is x = 20.

First, we'll add 3 to both sides of the equation:

x/2 - 3 + 3 = 7 + 3
