Answer 1

Answer:

x = 7

Step-by-step explanation:

Solve for x over the real numbers:

(3 x)/(2 x - 2) = 14/8

14/8 = 7/4:

(3 x)/(2 x - 2) = 7/4

Cross multiply:

12 x = 7 (2 x - 2)

Expand out terms of the right hand side:

12 x = 14 x - 14

Subtract 14 x from both sides:

-2 x = -14

Divide both sides by -2:

Answer:  x = 7
