Solve the equation 12 + 2n = 20 for n. a) -4 b) 0 c) 1 d) 4

Hey there.

12 + 2n = 20
Subtract 12 from both sides of the equation. This isolates our variable.
2n = 8
Divide both sides by 2, the number that's being multiplied by our variable. This isolates and solves for our variable.
n = 4; Your answer is D.)

I hope this helps!
