Question

200 + 10x = 120 + 15x now solve the equation to find x, the number of hours that both companies will charge the same ammount

Answer 1

16

Explanation:

Given the equation,
`200 + 10x = 120 + 15x`, let's solve for x as follows,

Subtract 200 from both sides

`200 + 10x - 200 = 120 + 15x - 200`

`10x = - 80 + 15x`

Subtract 15x from both sides

`10x - 15x = - 80 + 15x - 15x`

`-5x = - 80`

Divide both sides by -5

`(-5x)/(-5) = (-80)/(5)`

`x = 16`
