The equation that is equivalent is -2+(-7).
Hello there!
I see you got some work done already, but I guess you just wanted to double check! :)
3n + 8 = 20
3n = 20 -8 (Subtract 8 on both sides).
3n = 12 (Combine like terms).
n = 4 ( divide both sides by 3)
There you have your answer! :D
Hope this helped!
