The elimination method is a sufficient way to solve problems. 

2x+y= 20
6x-5y=12

Add 5y to the one equation.

2x+6y= 20
6x= 12

Subtract 2x from both sides. 

6y= 20
4x= 12

Divide 6 by 20. 
y= 3.3 

Divide 4 by 12.
x= 3

I hope this helped you!

Brainliest answer is appreciated!

No, no value for x will result in you getting the same amount of money
I.e. on the first day if x =2 you earn 33. on the second day you would've earned 44. Of course this may be wrong so best to double check

Vikki [24]

Answer:

They took 4,180 minutes total to complete the course.

Step-by-step explanation:

The average time is given by the sum of each individual time of the members divided by the number of members on the group. So if we want to know the total time they took to complete the course we need to take the average and multiply it by the number of people in the group. So we have:

total time = average*number of members = 110*38 = 4180 minutes

They took 4,180 minutes total to complete the course.

trasher [3.6K]
<h2>Answer:</h2>

<em>Then the -q would be </em><em>-8.</em><em> </em>

It is because there is negative sign before the variable.
