<span>Subtract y from both sides to get:
0 = 3x+y

subtract 3x from both sides to get:
y = -3x

It is a function.</span>
As per the problem we have
250g of cheese costs £3.60.
and we have been asked to find how much will 350g cost?
Since , 250g of cheese costs £3.60.
So 1g of cheese will cost £
Hence 350g of cheese will cost £
On simplification, we get
350g of cheese will cost=£5.04
Use an equation of ratios to solve this:
12 cm 9 cm
---------- = ---------
x 8 cm
Cross multiplying, 9x = 96, and x = 32/3 cm (10 2/3 cm).
