Answer: 7

Step-by-step explanation:

For L to be parallel to M, ( 7x + 9 ) must be equal to ( 8x + 2 ) because the two angles are corresponding to each other.

Equate both equation. That is,

7x + 9 = 8x + 2

Collect the like terms

7x - 8x = 2 - 9

- x = - 7

The minus sign will cancel out

X = 7

Therefore, the value of x that will make L||M is 7
