Question

5/7x + 4 = 8 solve it

Answer 1

`(5)/(7)x+4=8`

To solve this, first we have to substract 4 in both sides of the equation:

`(5)/(7)x+4-4=8-4`

And now we have

`(5)/(7)x=4`

And now we multiply by 7/5 both sides (or divide by 5/7, it's the same in other words)

`(5)/(7)\cdot(7)/(5)x=4(7)/(5)`

Then we have:

`x=(28)/(5)=5.6`

The answer is x = 5.6
