Question

- The cost of four chair and five table Rs 3200 find
linear equatione two variable
and find solutions and draw its graph?

​

Answer 1

Step-by-step explanation:

Let the cost of chair be 'x' and cost of table be 'y'.

So the linear equation will be

- 4x + 5y = 3200

In First case

if x=5 then

4x + 5y = 3200

4(5) + 5y = 3200

5y = 3200 - 20

y= 3180/5

y=636

therefore,

A ( 5 , 636 )

In second case

if x = 10 then

4x+5y =3200

4(10) + 5y = 3200

5y=3200-40

y = 3160/5

y = 632

therefore ,

B ( 10 , 632 )

now we can plot these coordinates in graph

hope u will understand this answer..............
