amm1812

Answer:

maximum is 16,853 cell phones

Use properties of equality to Solve 7+3x = 5x+13 for x
mario62 [17]
We basically have to cancel values on both sides until they are both on common ground.

7 + 3x = 5x + 13

-7 from both sides...

3x = 5x + 6

-5x from both sides...

-2x = 6

/-2 from both sides...

x = -3


Hope this helps!
