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
