Answer:
x=-5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
12 gallons $3.75 per gallon times 12 equals 45 plus 6 which is the car wash amount it’s $51.
84 = x% * 600
84 = x/100 * 600
84 = x * 6
6x = 84
Divide 6 on both sides.
x = 84/6
x = 14
