2x-12=x^2+x another question is 3.5x=20-2.5x

1) No solution

2x-12=x^2+x

Subtract -2x from both sides.

-12=x^2-x

Add 12 to both sides.

0=x^2-x+12

If you were to do the umbrella method there is no other way to simplify this expression.

2) 10/3

3.5x=20-2.5x

Add 2.5x to both sides.

6x=20

Divide 6 to both sides.

10/3=x

1. Has no soultion.

2. x-10/3

Hope that help!!!
