Answer 1

Let the cost of computer be currency x
and that of washing machine be currency y.

According to first situation,
x + y = 8500

Also, given that
computer = 500 'more than' 4 'times' machine.
x = 500 + 4 × y
x = 500 + 4y

So, the pair of linear equations in two variables to find the cost would be this:

x + y = 8500 ; x = 500 + 4y

Answer 2

linear equation is 5x+500=8500
as let,
the cost of the washing machine=x
