solve

the quantity x minus nine divided by three equals negative seven

1 answer

To solve the equation `(x - 9) ÷ 3 = -7`, we can start by multiplying both sides by 3 to eliminate the fraction:

3 * (x - 9) ÷ 3 = -7 * 3

This simplifies to:
x - 9 = -21

Next, we can isolate x by adding 9 to both sides:

x - 9 + 9 = -21 + 9

This simplifies to:
x = -12

Therefore, the solution is x = -12.
