Answer:
No solution
Step-by-step explanation:
Step 1: Write equation
10 + 6x = 15 + 9x - 3x
Step 2: Solve for <em>x</em>
- Combine like terms: 10 + 6x = 15 + 6x
- Subtract 6x on both sides: 10 ≠ 15
Here, we see that <em>x</em> would equal no solutions. You can also think of it as parallel lines; they have the same slope but different y-intercepts, so they will never intersect.
