Answer:

B

Explanation:

Given

(3x)/(4) +
(2x)/(3) = 51

Eliminate the fractions by multiplying through by the lowest common multiple of the denominators 4 and 3

The lowest common multiple of 3 and 4 is 12

12 ×
(3x)/(4) + 12 ×
(2x)/(3) = 12 × 51

9x + 8x = 612

17x = 612 ( divide both sides by 17 )

x = 36 → B
