5x +7/2 = 3x/2 -14

10x+7/2 = 3x-28/2

2(10x+7) = 2(3x-28)

20x +14 = 6x - 56

20x -6x = -56 - (14)

14x = -70

x = -70/14
x = -5

Hope it helps you friend .
Have a nice day.

Hey friend,
Here is the answer:
 \frac{5x + 7}{2}  =  \frac{3x}{2 - 14}  \\  \\  5x + 7 =  \frac{3x}{ - 12}  \times 2 \\  \\ 5x + 7 =  \frac{x}{2}  \\  \\ 5x =  \frac{x}{2}  - 7 \\  \\  5x =  \frac{x - 14}{2}  \\  \\  5x \times 2 = x - 14 \\  \\ 10x = x - 14 \\  \\ 10x - x =  - 14 \\  \\ 9x =  - 14 \\  \\ x =  \frac{ - 14}{9}  \\  \\ in \: decimal \\ x = 1.55

Hope this helps!!!
