Answer:
CM = 3
MG = 15
CG = 18
Step-by-step explanation:
CM = x
MG = x + 12
C to G equals 4x + 6
CG = 4x + 6
And CM + MG (CG) also equals 2x + 12
CM + MG = 2x + 12
4x + 6 = 2x + 12 (solve for x)
Subtract 2x from both sides.
2x + 6 = 12
Subtract 6 from both sides.
2x = 6
Divide by 2
x = 3
CM = (3)
MG = 3 + 12 = 15
CG = 4(3) + 6 = 18
