Answer:
Infinitely many.
Step-by-step explanation:
Combine like terms as shown below
x + <em>12</em> + 2x = <em>20</em> + 3x - <em>8</em>
Side one
x + 2x = 3x
Side two
<em>20 - 8 = 12</em>
Set the equation up again
3x + <em>12 </em>= 3x + <em>12 </em>
The equation is the same on both sides which means that the equation cancels itself out.
3x - 3x = 0 and 12 - 12 = 0
0 = 0 so there is infinitely many solutions because both sides equal the same thing.
