Ex.4.2 Q.2

Write four solutions for each of the following equations:

(1) 2x + y = 7

(2) πx + y = 9

(3) x = 4y

(1) 2x + y = 7

When x = 0,

2(0) + y = 7

=> 0 + y = 7

=> y =7

So, the solution is (0, 7).

When x = 1,

2(1) + y = 7

=> y = 7 – 2

=> y = 5

So, the solution is (1, 5).

When x = 2,

2(2) + y = 7

=> y = 7 – 4

=> y = 3

So, the solution is (2, 3).

When x = 3,

2(3) + y = 7

=> y = 7 – 6

=> y = 1

So, the solution is (3, 1).

(2) πx + y = 9

When x = 0

π (0) + y = 9

=> y = 9 – 0

=> y = 9

So, the solution is (0, 9).

When × = 1, π (1) + y = 9

=> y = 9 – π

So, the solution is {1, (9 – π)}

When x = 2,

π (2) + y = 9

=> y = 9 – 2π

So, the solution is {2, (9 – 2π)}

When × = –1,

π (–1) + y = 9

=> -π + y = 9

=> y = 9 + π

So, the solution is {–1, (9 + π)}

(3) x = 4y

When x = 0, 4y = 0

=> y = 0

So, the solution is (0, 0).

When x = 1, 4y = 1

=> y = 0

So, the solution is (0, 0)

When x = 4,

4y = 4

=> y = 4 ÷ 4

=> y = 1

So, the solution is (4, 1)

When x = -4,

4y = -4

=> y = -4 ÷ 4

=> y = -1

So, the solution is (4, -1).
