Please answer 5 and 6!
WILL GIVE BRAINLIEST :D

First one is 70 I believe.

Step-by-step explanation:

5. 35x+10

6. 14a+6b

This system will have 1 solution <==

** if it were to end like 0 = 4, or 2 = -3no variables and numbers that dont equalthis means no solutions.

** if u were to end up with 5 = 5, or -9 = -9...no variables and numbers that do equal, then u will have infinite solutions

** but if u end with y = -2 or x = 5...a variable equaling a number, then u will have 1 solution
