To find y, substitute x in for y in one of the equations
add 5 to both sides
Divide both sides by 2

Answer:
You each will pay $40.35
Step-by-step explanation:
First you take the total $134.50 and divide it by 4 which is you and your three friends.
This will give you 33.625 which is the amount each of you will pay without tip.
To find the tip you take 20% from $134.50 which will give you 26.9 and when you divide that by the four of you it will give you 6.725.
Then you take your amount 33.625 plus your tip 6.725 which will give you $40.35.
The total you all will pay will be $161.40 this is the total $134.50 plus the tip $26.90.

Hey there,
a-7=3(b+2), we do 3 times b and 3 times 2 according to the rule.
a-7=3b+6 we change + to - and - to + when move nums from 1 side to another one.
a=3b+13 we get the solution.
Hope this helps :)
