To solve the equation "half a number plus 9 is -7," we can set up the equation as follows:
\[
\frac{x}{2} + 9 = -7
\]
Now, let's solve for \(x\):
1. Subtract 9 from both sides:
\[
\frac{x}{2} = -7 - 9
\]
\[
\frac{x}{2} = -16
\]
2. Multiply both sides by 2 to solve for \(x\):
\[
x = -32
\]
So, the number is \(-32\).
\[
\frac{x}{2} + 9 = -7
\]
Now, let's solve for \(x\):
1. Subtract 9 from both sides:
\[
\frac{x}{2} = -7 - 9
