Question

5x+4y=20 Three solutions of this

Answer 1

Step-by-step explanation:

Firstly, transpose one of variable term to RHS,

Now the equation becomes

5x = 20 - 4y

Now, substitute x as 0 and get value of y,

therefore (1) x= 0, y = 5

similarly, 5x= 20- 4(0)

therefore, (2) x=4 , y=0

Now, take (3)x= 2,

then (3)y= 2.5

Pro tip: Always make equation easy by transposition of any one variable term and get corresponding values of other variable. Also take x as 0 and y as 0 for quick solutions. Hope it helps you.
