Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
4x + 6x - 7 = 23
Step 2: Solve for x
- Combine like terms: 10x - 7 = 23
- Add 7 to both sides: 10x = 30
- Divide both sides by 10: x = 3
Step 3: Check
Plug in x to verify it's a solution.
4(3) + 6(3) - 7 = 23
12 + 18 - 7 = 23
30 - 7 = 23
23 = 23
