Question

24. What are the values of x and y for the following pair of linear equations ? . 3x+2y - 7 = 0. . . 4x+y-6 = 0. . (a) 1 and 2. . (b) 2 and 2. . (c) 1 and 1. . (d) -1 and -1​

Answer 1

Answer:

option 1) 1 nad 2

Step-by-step explanation:

eq.1 ___ 3x +2y -7 =0

eq.2___ 4x + y - 6 =0

by elemenation method

making y same in both equation

3x + 2y = 7

8x + 2y = 12

(-) (-) (-)

- 5x -0 =-5

-5 x = -5

x = 1

puttingvalue of x in eq. 2

4x + y - 6 =0

4 + y = 6

y = 2

x and y are 1 and 2 respectively
