Step-by-step explanation:

DG is the total measurement of the line. M is a point inbetween D & G

2x + x - 2 = 7

Simplify. Combine likke terms

(2x + x) - 2 = 7

3x - 2 = 7

Isolate the x. First, add 2 to both sides

3x - 2 (+2) = 7 (+2)

3x = 9

Isolate the x. Divide 3 from both sides

(3x)/3 = (9)/3

x = 9/3

x = 3
