Question

determine the solution set of -3+7=10 or 3x-9=0

Answer 1

To solve the given expression, we will solve each equation separately.

1. **First equation:** \(-3 + 7 = 10\)

This is a simple arithmetic statement:
\[
-3 + 7 = 4 \quad \text{(not equal to 10)}
\]
So this part of the expression is false.

2. **Second equation:** \(3x - 9 = 0\)

To solve for \(x\), we add 9 to both sides:
\[
3x = 9
\]
Then, divide by 3:
\[
x = 3
\]

Now, we combine the results from both equations. The first part is false (not part of the solution), but the second part provides the solution \(x = 3\).

Thus, the solution set is:
\[
\{3\}
\]
