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
