Hello from MrBillDoesMath!

Answer:  x = +9

Discussion:

-59 = 3x  -2 (7x -20)  or

-59 = 3x - (2*7)x  - 2 ( -20)  or

-59 = 3x -14x + 40  or

-59 = -11x + 40.           Subtract 40 from each side

-59 - 40 = -11x  or

-99 = -11x

or x = + 9



Thank you,

MrB

Answer:

x = 9

Step-by-step explanation:

-59 = 3x - 2(7x - 20)

-59 = 3x - 14x + 40 ;(distributive property)

-59 = -11x + 40

-59 - 40 = -11x

-99 = -11x

9 = x
