Fig. 3.4
EXERCISE 3.1
1. Aftab tells his daughter, "Seven years ago, I was seven times as old as you were then
Also, three years from now, I shall be three times as old as you will be." (Isn't this
interesting?) Represent this situation algebraically and graphically,
2. The coach of a cricket team buys 3 bats and 6 balls for 3900. Later, she buys another
bat and 3 more balls of the same kind for 1300. Represent this situation algebraically
and geometrically
3. The cost of 2 kg of apples and Ikg of grapes on a day was found to be + 160. After a
month, the cost of 4 kg of apples and 2 kg of grapes is 7300. Represent the situation
algebraically and geometrically
Graphical Method of Solution of a Pair of Linear Equations
the previous section, you have seen how we can graphically represent a pair of
car equations as two lines. You have also seen that the lines may intersect, or may
parallel, or may coincide. Can we solve them in each case? And if so, how? We
all try and answer these questions from the geometrical point​

Answer 1

Answer:

As the God of geometry said and I court "do not make it complicated make it compel" uncouth
