1. Perform the indicated multiplications:
18 - 4.5x + 36 = 202 - 7.5x - 70
2. Combine like terms on the left side, and do the same on the right side:
54 - 4.5x = 132 - 7.5x
3. Isolate x: Add 7.5x to both sides of this equation, and then subtract 54 from both sides:
3x = 78
4. Divide both sides of this equation by 3: x = 78/3 = 26
5. The solution is x = 26.
