Solve the equation x+12+2x=20+3x−8.

Mathematics
1 answer:
LenaWriter [7]3 years ago

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.
