Answer:
[tex]2x + 4 = 22[/tex]
[tex]or \: 2x = 22 - 4[/tex]
[tex]or \: 2x = 18[/tex]
[tex]or \: x = \frac{18}{2} [/tex]
[tex]therefor \: x = 9[/tex]
x = 9
Step-by-step explanation:
Since M is the midpoint of AC then
AM = MC , that is
2x + 4 = 22 ( subtract 4 from both sides )
2x = 18 ( divide both sides by 2 )
