Answer:
x=3
Step-by-step explanation:
6x - 2 = x + 13
subtract 1x from both sides
5x - 2 = 13
isolate the 5x by adding 2 to both sides
5x = 15
finnaly devide both by 5
x = 3
X = the number of months the tire was used
y = the thickness of the tire tread
y = -(3/7)x + 20
Substitute x for 20 (the number of months the tire was used) and solve for y.
The next question: Substitute x for 49 (the number of months the tire was used) and solve for y.
