Question

Point G lies between points F and H on . If the length of FH is 18 units, what is the value of x? 3 4 5 6

Answer 1

Point G lies between points F and H on .

 

If the length of FH is 18 units, what is the value of x?

 the answer is 3 .

Answer 2

see the attached figure to better understand the problem

we know that

$FH=FG+GH$

$FH=18$ -------> equation $1$

$FH=4x+2x$

$FH=6x$ -------> equation $2$

equate equation $1$ and equation $2$

$18=6x$

$x=3$

therefore

the answer is

$x=3$
