We will see.

9X - 8 = 69 - 2X

add 2X to each side

2X + 9X - 8 = 69 - 2X + 2X

11X - 8 = 69

add 8 to each side

11X - 8 + 8 = 69 + 8

11X = 77

divide both sides by 11

X = 7

Now, check in original equation

9(7) - 8 = 69 - 2(7)

63 - 8 = 69 - 14

55 = 55

so, it checks and 7 is a solution here
