Step-by-step explanation:

$7 + \frac{x}{3} = 8 + \frac{x}{4} \\ \\ \frac{21 + x}{3} = \frac{32 + x}{4} \\ \\ 4(21 + x) = 3(32 + x) \\ \\ 84 + 4x = 96 + 3x \\ \\ 4x - 3x = 96 - 84 \\ \\ x = 12$

Answer 2

Answer:

The value of x is 12

Step-by-step explanation:

7+x/3=8+x/4

x/3 - x/4 = 8 - 7

(4x - 3x)/12  = 1

x/12 = 1

x = 12
