and two chocolates for ₹7. Represent this situation in the form of a pair of linear
equations. Find the price of one pencil and that of one chocolate graphically and
verify the result by using
Substitution Method.

Answer 1

Answer:

LET COST OF PENCIL ✏️ BE X

AND THE COST OF CHOCOLATE BE Y

2X+3Y=11-----1(EQ)

X+2Y=7-----2(EQ)

Step-by-step explanation:

2X+3Y=11------(1)

X+2Y=7---------(2). X 2

2X+3Y=11

2X+4Y=14-------(3)

-----------------------------

-Y= -3

-----------------------------

Y=3

SUBSTITUTE VALUE OF Y IN EQ(1)

2X+3(3)=11

2X+9=11

2X= 11-9

2X =2

X=2/2

X=1
