Question

Answer for this question
The value of a colored paper is 17 more than one third of the value of a white paper. Express two statements of this statement in the form of a compact equation.

Answer 1

Answer:

${x} - 3{y} + {21}$

Step-by-step explanation:

Let the cost of white paper be rs. x

And the cost of colour paper be Rs. y

Now, according to the question

cost of colour paper = (1/3) × cost of white paper + 7

or, y = (1/3)x + 7

or, 3y = x + 21

or x - 3y + 21 = 0

This is the required linear equation in 2 variables.
