-10x + 3y = 34
y = -8x

Answer

Step 1: Simplify both sides of the equation.

−10x + 3(−8x) = 34

−10x + −24x = 34

(−10x + −24x) = 34 (Combine Like Terms)

−34x=34

Step 2: Divide both sides by -34.

x=−1

x=−1

So the pair of coordinates for your answer is (-1, 8)

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the answer i believe is 27 units.
