Question

What is y=-7/5x-3 when y=-10

Answer 1

`x=(1)/(5)`

Explanation:

Step 1 :-

given
`y= (-7)/(5 x) -3`

substitute given y=-10

`-10+3 = (7)/(5 x)`

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

cancelled (-7) on both sides, we get

`1= (1)/(5 x)`

cross multiplication, we get

`5 x =1`

`x=(1)/(5)`

Final answer:-
`x=(1)/(5)`

verification:-

given
`y= (-7)/(5 x) -3`

substitute
`x=(1)/(5)`

we get y= -10
