A carpet cleaner charges $37 to travel to a customer's home in $15 per room cleaned if the carpet cleaner charge $142 how many rooms did he clean write and solve an equation to find the answer

this is a good question! i'll do some research and come back when i have the answer!

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal

1.m=2

2.m=-6

3.m=3

4.m=1/2
