Answer:
Step-by-step explanation:
a)
As given y=mx lets replace mx with y in the first equation
2y=n => y=n/2, replace y with n/2 => mx=n/2, thus x=n/2m
b)
As given y=nx lets replace y with nx in the first equation
x+n^2x=m => x(n^2+1)=m = > x=m/(n^2+1), thus y= n*m/(n^2+1)
c) Replace y with nx => mx-nx=n => x(m-n)=n = > x=n/(m-n), thus y=n^2/(m-n)
Here you go :) I sent the work in the picture below
15x<130+20, 15x<150 divided both sides by 15 ,the answer is 10
