Answer:

B

Step-by-step explanation:

Given

[tex]\frac{3x}{4}[/tex] + [tex]\frac{2x}{3}[/tex] = 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 × [tex]\frac{3x}{4}[/tex] + 12 × [tex]\frac{2x}{3}[/tex] = 12 × 51

9x + 8x = 612

17x = 612 ( divide both sides by 17 )

x = 36 → B
