You can change all of these to decimals and then solve or get common denominators.
8.75 + n + 2.375 + 4.5 = 23.125
15.625 + n = 23.125
Subtract 15.625 from both sides
n = 7.5
She’s incorrect I’m pretty sure u divide 20 and 60.
4n-40=7(-2n+2)
4n-40=-14n+14
subtract -4n from both sides
-40 = -18n +14
subtract -14 from both sides
-54=-18n
divide both sides by -18
3 = n
