4x + 8 = 2x + <u>7</u> + 2x <u>- 20</u>
4x + 8 = −13 + 4x
-4x - 4x
_________________
8 ≠ −13; NO SOLUTION
__________________________________________________________
25 - 4x = <u>15</u> - 3x + <u>10</u> - x
25 - 4x = −4x + 25; INFINITELY MANY SOLUTIONS
__________________________________________________________
6x + 4x - 6 = 24 + 9x
10x - 6 = 24 + 9x
-10x - 10x
_________________
−6 = 24 - x
-24 - 24
___________
−30 = −x
30 = x; ONE SOLUTION
