8n - 24 = -2 (1 - 3n) + 2n

0=22

Step-by-step explanation:

Step 1)

8n+−24=(−2)(1)+(−2)(−3n)+2n

8n+−24=−2+6n+2n

8n−24=(6n+2n)+(−2)(Combine Like Terms)

8n−24=8n−2

Step 2)

8n−24−8n=8n−2−8n - Subtract 8n from both sides.

8n−24−8n=8n−2−8n

−24=−2

Step 3)

−24+24=−2+24 - Add 24 to both sides.

0=22
