Question

find the solution for a pair of linear equation by any suitable method 3 X + 2 Y - 7 which is equals to zero 4 x + Y - 6 is equals to zero​

Answer 1

Answer:

X=1 and y=2 you will get this answer

Answer 2

Answer:

3x + 2y - 7 = 0------(1)

4x + y - 6 = 0------(2)

multiply eq.(2) by 2

(4x + y - 6 = 0)×2

8x + 2y - 12= 0------(3)

subtract (1) from(3)

8x + 2y - 12= 0

3x + 2y - 7 = 0

(-). (-). (+)

5x - 5 = 0

x=1

pu x=1 in eq. (1)

3x + 2y - 7 = 0

3(1)+2y=7

2y=7-3

y=4/2

y=2
