Question

Calculate the value of x, given line segment FM = 4x and line segment MN = 7x – 21.

x = 7

x = 5

x = 6

x = 8

Answer 1

x=7 b/c you have to put all the x's on one side so you'll get -3x=-21 and you just divide by -3 and you get 7. 

Answer 2

I am not sure about this answer but i think X equals seven ( 7 )
