Answer:
Step-by-step explanation:
A) 4x + 6 = 2x - 12
Subtract 6 from both sides
4x + 6 - 6 = 2x - 12 -6
4x = 2x - 18
Subtract 2x form both sides
4x - 2x = 2x - 18 - 2x
2x = -18
B) 24 = 6x - 18
6x - 18 = 24
6x - 6*3 = 24
6(x - 3) = 24
Divide both sides by 6

x - 3 = 4
He earns $400 per week.
In addition, he gets $150 per car (x).
"x" is the number of cars.
400 + 150x
If he earned $1450 last week, then
400 + 150x = 1450
First, subtract 400 from both sides.
150x = 1050
Now divide both sides by 150.
x = 7
