Write four solution for the following equation
x=4y

Hint: In these types of questions always remember that x is directly related to y i.e. as x changes y will also change.
Complete Step-by-Step solution:
Given equation
x=4y
Now put y = 0 will get
x=4(0)
x=0
∴ (0,0) is one solution
Now put y = 1 will get
x=4(1)
x=4
∴ (4,1) is second solution
Now put y = 2 will get
x=4(2)
x=8
∴ (8,2) is third solution
Now put y = 3 will get
x=4(3)
x=12
∴ (12,3) is fourth solution
Hence (0,0),(4,1),(8,2),(12,3) are the four solution
Note: When x and y are directly related just assume and assign a value to the independent variable (either x or y) and write the value of the dependent variable.
