Question

simplify urgent please ​

Answer 1

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

Answer 2

Answer:

x = 12

Step-by-step explanation:

7 + x/3 = 8 + x/4

21 + x / 3 = 32 + x / 4

4(21 + x) = 96 + 34

4x - 3x = 96 - 84

x = 12
