Tell whether the equation has one, zero, or infinitely many solutions.
12n + 22 = 10n + 2n + 7

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

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

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
