Answer:

x = 9

Explanation:

Solve for x:

11 - x/3 = 8

Put each term in 11 - x/3 over the common denominator 3: 11 - x/3 = 33/3 - x/3:

33/3 - x/3 = 8

33/3 - x/3 = (33 - x)/3:

(33 - x)/3 = 8

Multiply both sides of (33 - x)/3 = 8 by 3:

(3 (33 - x))/3 = 3×8

(3 (33 - x))/3 = 3/3×(33 - x) = 33 - x:

33 - x = 3×8

3×8 = 24:

33 - x = 24

Subtract 33 from both sides:

(33 - 33) - x = 24 - 33

33 - 33 = 0:

-x = 24 - 33

24 - 33 = -9:

-x = -9

Multiply both sides of -x = -9 by -1:

(-x)/(-1) = 9

(-1)/(-1) = 1:

Answer: x = 9
