Answer:

x = 4 2/7

Explanation:

2/3 x= -1/2x+5

Add 1/2 to each side

2/3 x 1/2 x = -1/2x+1/2x+5

2/3 x +1/2x =5

Get a common denominator

2/3x *2/2 + 1/2 *3/3 = 5

4/6x + 3/6x = 5

7/6x = 5

Multiply each side by 6/7 to isolate x

6/7 *7/6x = 5 *6/7

x = 30/7

Change to a mixed number

x = 28/7 + 2/7

x = 4 2/7
