Question

How do you solve this problem??3y+2+2y+5=

Answer 1

First of all, you aren't solving. You must of two sides of an equation in order to solve.

You are actually simplifying.


Ok. now here is the math part...

3y+2+2y+5
5y+2+5 (add the 'y' terms)
5y+7 (add the constants)

Answer: 5y+7

YOU CAN'T ADD 5y+7
Explanation:
You can ONLY add like terms. You CAN'T do 5y+7 because 7 doesn't have a y in front of it.

By adding those together, you are violating 'order of operations' due to the fact that y is a variable and variables represent numbers.

To put this into perspective, I will give y a value...
Let's say that y=3
If you plugged 3 into the expression for y...
5y+7, for y=3
You would do this
5(3)+7=15+7=22
NOT
5(3)+7=12(3)=36

Answer 2

First, re-arange the like terms:
3y + 2y + 2 + 5.
Now you can solve:
3y + 2y = 5y.
2 + 5 = 7.
You cannot add 5y and 7 since they are not like terms. 7 does not have a Y on front, so it stays:
5y + 7
