In the equation 5n-11=4n+20, n is equal to 31.
4n + 1 = 12 + 5n First, let's get all n terms on one side and all non-n terms on the other side. Start off by subtracting 4n from each side. 1 = 12 + n Now subtract 12 from each side. -11 = n
5n-2+2=4n 5n=4n n=0
it equals -4n
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
4n

5n - n = 8 + 4 ie 4n = 12 so n = 3
5n+15 = 25 5n = 25-15 5n = 10 n = 2
-2n
-5n+9=-46 -5n+9-9=-46-9 -5n=-55 -5n/-5=-55/-5 n=11
