The prices of two radios are in the ratio x:y When the prices are both increased by £20, the ratio becomes 5:2 When the prices are both reduced by £5, the ratio becomes 5:1 Express the ratio x:y in it's lowest terms.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
