Question

Penciks cost x pence and oebs cost 5 pence more than pencils.
1) Write in algebra the cost of 3 pencils?
2)What is the cost of a pen?
3)What is the total cost of 3 pencils and a pen?
please give me full method of this whole question.​

Answer 1

Step-by-step explanation:

I can give you the equation and will tell how you can represent it but I cannot post the graph.

Cost if 1 pen = RS. x

cost of 3pens = RS. 3x

Cost of 1 pencil = RS. y

Cost of 2 pencils = RS. 2y

Total sum of the two costs = RS. 34

Therefore,

3x + 2y = 34.

The above is the equation.

To construct it's graph,

Find any two points.

For first point

Let x = 10.

30 + 2y = 34.

y= 2.

Point = (10,2)

Let x = 8.

24 + 2y = 34.

y = 5.

Point = (8,5)

Join these two points to get the line planted on the graph.
