43/80 is the reduced faction. I hope this helps:)
Step by step:
3n-18=4n+18
~subtract 3n from both sides:
-18= n + 18
~subtract 18 on both sides
answer: -36=n
So first we have to subtract 3y from 21 cause the oppisit of addition which is subtraction so you get 18y when we divide that with -8y and get y=2.25y
2(x-5) + 4x - 7 = 7
2x-10 + 4x -7 -7 =0
6x - 24 = 0
6x = 24
x= 24/6
x= 4
Micah's answer is incorrect because X=4
