Answer:
x = 6.1
Step-by-step explanation:
-4.5 (x - 8.9) = 12.6
Firstly, we need to distribute -4.5 to (x - 8.9), resulting in:
-4.5x + 40.05 = 12.6
Afterwards, we subtract 40.05 on both sides to single out x:
-4.5x + 40.05 - 40.05 = 12.6 - 40.05
-4.5x = -27.45
The opposite of multiplication is division, therefore:
-4.5x / -4.5 = -27.45 / -4.5
Resulting in:
x = 6.1
