Question

Solve the proportion. 7/5=6/x + 4

Answer 1

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
