Topic : Linear equations in two variables.
Given :
- 2x - y = 3 ––– (i)
- - x - y = 3 ––– (ii)
Solution :
Now,
(i) – (ii)




Now, substituting the value of x in Eq (i) :




Therefore,
- <u>The value of x = 0 and y = -3</u>

If we know that Laura's canvas is square, and one side is 22cm,
area of a square is l*w, with a special case of l=w
the area will be
A= l*w=22*22=484cm^2
also, Asquare is=l^2
3x+2y=5.44
it's a two variable problem which can't be solved algebraically unless you are given the weight of one of the balls.
