Answer:

x=9

Step-by-step explanation:

x + 10 = - x + 28

Add x to each side

x+x + 10 = - x+x + 28

2x+10 = 28

Subtract 10 from each side

2x+10-10 = 28-10

2x = 18

Divide by 2

2x/2 = 18/2

x = 9

Answer:

x = 9

Step-by-step explanation:

x + 10 = - x + 28

Subtract 10 from both sides

x = -x + 18

Add x to both sides

2x = 18

Divide by 2 on both sides

x = 9

I hope this helps!!!
