Answer:
part A:
M = 4(2x + 6)
= 8x + 24
part B:
option 1) i think the x value is equal for both M and N since they have the value 8.
option 2) If you meant to solve M and N with an EQUATION then here's your answer:
8x+24 = 8x+10
24≠10 (you subtract 8x when taken to the other side)
So, the answer would be NO SOLUTION
