Answer:

The answer is that x = -20.

Step-by-step explanation:

The equation:

5/2x + 1/2x = 10 + 7/2x

6/2x = 10 + 7/2x

-7/2x + 6/2x = 10

-1/2x = 10

-1/2x * -2 = 10 * -2

x = -20

Proof:

5/2*-20 + 1/2*-20 = 10 + 7/2(-20)

-50 + (-10) = 10 + (-70)

-50 - 10 = 10 - 70

-60 = -60
X=-20

Combine like terms
6/2x=10+7/2x
Subtract 6/2 from both sides
0=10+1/2x
Subtract 10 from both sides
-10=1/2x
Divide 1/2 by both sides to isolate the variable and you’ll get
X=-20
