we are given


(7)/(5) =(6)/(x+4)

we are given to solve for x

so, we isolate x on anyone side

step-1:

Multiply both sides by x+4


(7)/(5)* (x+4) =(6)/(x+4)* (x+4)


(7)/(5)* (x+4) =6

step-2:

Multiply both sides by 5


(7)/(5)* (x+4)* 5 =6* 5


7 (x+4)=30

step-3:

Distribute 7


7x+28=30

step-4:

Subtract both sides by 28


7x+28-28=30-28


7x=2

step-5:

Divide both sides by 7


x=(2)/(7)..............Answer
