Answer:

y = 20x + 5

Step-by-step explanation:

X = Y/20 - 1/4

In this type of expression you will first of all find the LCM of the right hand side

x = y - 5/ 20

the next thing to do is to cross multiply

we have,

20x = y - 5

dont forget we are to solve for y in the equation, so to solve for y we have

20x + 5 = y

therefore y will be expressed in terms of x as written below

y = 20x + 5
