Answer:

11

Step-by-step explanation:

Since M is on LN,

LM + MN = LN.

[tex](2x+7)+3x=4x+9[/tex]

Remove brackets:

[tex]2x+7+3x=4x+9[/tex]

Add the x terms:

[tex]5x+7=4x+9[/tex]

Subtract 7 from both sides:

[tex]5x+7-7=4x+9-7[/tex]

[tex]5x=4x+2[/tex]

Subtract 4x from both sides:

[tex]5x-4x=4x+2-4x[/tex]

[tex]x=2[/tex]

[tex]LM=2x+7=2(2)+7=4+7=11[/tex]
