Answer:
x = -3
Step-by-step explanation:
2x-3=21+10x
Subtract 2x from each side
2x-2x-3=21+10x-2x
-3 = 21 +8x
Subtract 21 from each side
-3-21 = 21-21 +8x
-24 = 8x
Divide each side by 8
-24/8 = 8x/8
-3 =x
x=-3
First, Isolate and combine the x variables.
So, subtract 10x on both sides and get: -8x -3=21
Add 3 on both sides.
-8x=24
Divide 24 by -8
you should get: x=-3
