3. Pair of Linear Equations in Two Variables
Assignment
ASIGNMENT:
1. Solve the linear equation for x and y.
Type - I
(a) 148x + 231y = 527,
231x + 148y = 610
(b) 37x + 43y = 123
43x + 37y = 117
(c) 47x + 31y = 63
31x + 47y = 15
Type - II
(d) 2x + 3y = 7
2x - 3y = 1 Ans: x = 2, y = 1
(e) 5x – 6y = 3
3x + y = 11 Ans: x = 3, y = 2
(f) 8x + 3y = 17
11x + 2y = 17 Ans: x = 1, y = 3
(g) 17x – 8y = 2
9x – 4y = 2 Ans: x = 2, y = 4
(h) 3x + 4y = 43
2x – 5y = -25 Ans: x = 5, y = 7
(i) 7x + 9y -13 = 0
2x – 3y +13=0
(j) 4x – 3y +4 = 0
4x + 3y – 20 = 0
(k) 3x +y -5=0
2x –y -5 = 0
(l) 4x – y – 8 = 0
2x – 3y + 6 = 0
(m) 2x – 3y -4 = 0
x – y – 1 =0
(n) 2x –y= 2
4x – y = 4
(o) x - y +1 = 0
3x + 2y - 12
(p) 2x + 3y = 12
x – y = 1
(q) x + 2y = 5
2x – 3y = -4
