Answer:
No solution
Step-by-step explanation:
12n + 22 = 10n + 2n + 7
Combine like terms
12n+22=12n+7
Both sides have 12n so they cancel out, meaning whatever you put for n won't matter since 22 ≠ 7
Answer:
Zero
Step-by-step explanation:
Add the two variables on the right side, the numbers with a letter attached to them. You should have 12. Then subtract 12 from left to right or right from left. It will cancel out both sides.
Subtract 7 from 22, or 22 from seven. You'll get a numerical value, however there are no variables left, therefore your answer is zero
