Answer 1

X = 7

Explanation:

-11x - 6 + 20x = 57 (Collect like terms)

9x - 6 = 57 (Add 6 on both sides)

9x = 63 (Divide by 9 on both sides)

x = 7

-11(7) -6 + 20(7) = 57

-77 - 6 + 140 = 57

-83 + 140 = 57

57 = 57 √

Answer 2

Step 1: combine like terms
9x -6 = 57
Step 2: add 6 to both sides
9x = 63
Step 3: divide 9 to both sides
x=7
