First you can break down the percent and the time into a fraction
You can divide it by 2
so 2%/1 (2% in 1 minute)
Then you find the amount of time it would take to paint the whole bookcase

Answer:
Y = 1/4x-1
X = 4y-1
Step-by-step explanation:
layout the equations :
x+1/y = 4 y+1/x = 1/4
solve the equations, remember to switch sides switch signs solving the equations will give us the value of the letter
x+1/y = 4
x+1 = 4y
x=4y-1
***
y+1/x = 1/4
y+1 = 1/4x
y = 1/4x-1
