Hi there’s some math apps for this
<span>If y varies directly with x, the formula of the equation is y=ax, where a is a constant.
y=ax
(21)=a(7)
a=3
y=ax
y=(3)(-1.66)
y=-4.98, x=-1.66
If y varies inversely with x, the formula of the equation is y=a/x, where a is a constant
y=a/x
9=a/2.5
a=22.5
y=22.5/x
y=22.5/-0.6
y=-37.5
I hope this helped! =)
I hope you didn't mind but I got this from a website called: answers.yahoo.com but I got your answer.

➷ 9=5x-3+9
First, you would need to combine the like terms.
-3+9 = 6
9=5x+6
Next, you subtract 6 on both sides.
3=5x
Finally, you divide 5 on both sides to isolate x.
3/5=x
Final answer:
x=3/5
