To solve is relatively easy. All you need to do is divide both sides by 3 to get the x variable alone.
When you do that what you are left with is x = 4 - 4/3y
So you do
distribute
a(b+c)=ab+ac
9(x+5)=9x+9 times 5=9x+45
7(x-3)=7x+7 times -3=7x-21
so now we have
9x+45+7x-21
group like terms
9x+7x+45-21
add
16x+24
simplified is 16x+24
Answer:
A is irrational and I believe the rest are rational
If its has to be odd it would most likely be 29 times instead of 28
