For this case we must find the value of "x" of the following expression:

$3x-8 = \frac {8x + 4} {2}$

Multiplying by 2 on both sides of the equation:

$2 (3x-8) = 8x + 4\\6x-16 = 8x + 4$

Subtracting 8x from both sides of the equation:

$6x-8x-16 = 4\\-2x-16 = 4$

Adding 16 to both sides:

$-2x = 4 + 16\\-2x = 20$

Dividing between -2 on both sides:

$x = \frac {20} {- 2}\\x = -10$

x = -10

-7/8(-8/7)x-3/4=20(-8/7)

Step-by-step explanation:

-7/8(-8/7)x-3/4=20(-8/7)

x-3/4=-21 1/7

x=-21 4/28-21/28

x= 20 3/28

The other three are actually the same problem, and they all equal -23.7
