Answer:

3

Step-by-step explanation:

the whole line equals

5x-8 as well as x+3x-5

since it equals both we know the equation is

5x-8=x+3x-5 simplify to 4x-5

5x-8=4x-5

-5x.    -5x

-8=-1x-5

+5.     +5

-3= -1x

-/.     -/

3=x

we now can double check our work by putting 3 everywhere the x is

EG =7

FG= 4

making EF 3
