The tin of beans cost in pounds is 0.9 and two tin of beans cost in pounds, £ is 1.8.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Ed buys a box of eggs costing £2.80, two packs of bacon for £2.25 each and two tins of baked beans.
Let's suppose the cost of tins of baked beans is x
2.80 + 2×2.25 + 2x = 10 - 0.90 (100p = £1)
2.80 + 4.5 + 2x = 9.1
2x = 1.8
x = 0.9
Thus, the tin of beans cost in pounds is 0.9 and two tin of beans cost in pounds, £ is 1.8.
