ANSWER
3x+4y=10 …………..(1)
2x−2y=2 (or) x−y=1 …………(2)
(1) ⇒(3x+4y=10)1
(2) ⇒(x−y=1)3
_____________________
3x+4y=10
3x−3y=3
_____________________
7y=7
∴y=1
Put y=1 in (1) we get 3x+4×1=10
3x=10−4=6
∴x=36=2
Hence x=2,y=1.

Answer:
9/4 divided by 3/8 is 6
ans 3/5 divided by 2/3 is 0.9 sorry for not showing a explanation.
I am guessing your problem should read...
A) n = -5n + 90 (isolate the variables by adding 5n to each side)
+5n +5n
6n = 90 (since we don't want to know what 6n's are worth, divide by 6)
6n/6 = 90/6
n = 15
