Answer 1

It would take 5.5 months for the two cable companies to cost the same.

Explanation:

50x + 100 = 60x + 45

-45 -45

50x + 55 = 60x

-50x -50x

55 = 10x

/10 /10

x = 5.5

Answer 2

5.5 months

Explanation:

Let m be the number of months that pass.

We can write an equation to resemble this problem [ 100 + 50m = 45 + 60m ]

Steps to solve:

100 + 50m = 45 + 60m

~Subtract 100 to both sides

50m = -55 + 60m

Subtract 60m to both sides

-10m = -55

~Divide -10 to both sides

m = 5.5

Best of Luck!
