Question

Which equation has the solution x, equals, x = 3

3x + 8 = 41
4x - 2 = 10
9x + 1 = -28
2x + 3 = 30

Answer 1

Let's check each equation to see which one has the solution \( x = 3 \).

1. **For the equation** \( 3x + 8 = 41 \):
\[
3(3) + 8 = 41 \\
9 + 8 = 41 \\
17 \neq 41
\]
Not a solution.

2. **For the equation** \( 4x - 2 = 10 \):
\[
4(3) - 2 = 10 \\
12 - 2 = 10 \\
10 = 10
\]
This is a solution.

3. **For the equation** \( 9x + 1 = -28 \):
\[
9(3) + 1 = -28 \\
27 + 1 = -28 \\
28 \neq -28
\]
Not a solution.

4. **For the equation** \( 2x + 3 = 30 \):
\[
2(3) + 3 = 30 \\
6 + 3 = 30 \\
9 \neq 30
\]
Not a solution.

The equation that has the solution \( x = 3 \) is \( 4x - 2 = 10 \).
