Question

X − 7 = 46 − 9(x + 7)
x =

Answer 1

x = -1

Explanation:

x − 7 = 46 − 9(x + 7)

x - 53 = -9x - 63

10x = -10

x = -1

Answer 2

x=-1

Explanation:

x − 7 = 46 − 9(x + 7)

distribute

x-7 = 46 - 9x -63

Combine like terms

x-7 = -9x-17

Add 9x to each sid

x-7+9x = -9x+9x -17

10x-7 = -17

Add 7 to each side

10x -7+7 = -17+7

10x = -10

10x/10 = -10/10

x = -1
