HELP PLEASE I WILL MARK BRAINLIEST!! Solve The system of linear equations by substitution. Check your solution.

5. (-2,-1)   6. (1,2)  7.(12,6)

Step-by-step explanation:

5. x=−2, y=−1

6. x=1, y=2

7. x=12 and y=6

Step-by-step explanation:

I hope this helped!

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

step-by-step explanation:

simple you would first have to get   a negative number where as 1 to be multiplied by 24 and then you would have to multiply 6 time 4 and then repeat that process until you reach your term
