Question

a boy spends money on a purchase of pen and pencil a pen costs him ₹x and pencil ₹y the boy buys 4 pens and 6 pencils and spends ₹150 on them write a linear equation and draw its graph​

Answer 1

Answer:

Step-by-step explanation:

The Cost of one pen is Rs.x

Cost of 4 pens= 4*x

                         = Rs.4x

The Cost of one pencil is Rs.y

Cost of 6 pencils= 6*y

                            = 6y

4x+6y=150

x+y=150/4+6

x+y=150/10

x+y= 15

4x= 4*15=Rs.60

6y= 6*15= Rs. 90

4x+6y=150

60+90=150

150=150

hence, x+y=15
