M is between C and G. If CM = x , MG = x +12, and CG= 4x +6.

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

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
