Question

X+y=3 , 3x-2y-4=0 by determinant method find D

Answer 1

Here's your answer X=5 y=-2

Answer 2

Answer:

Step-by-step explanation:

X+Y =3....... 1

3X-2Y-4=O

3X-2Y=4.......2

Multiply equation 1 by 2

2×X+2×Y=2×3

2X+2Y=6.........3

Add eq 2 and 3,

3X-2Y=4

+

2X+2Y=6

_____________

5X = 10

X =10/5

X = 2

Place X=2 in eq. 1

2+Y = 3

Y =3-2

Y = 1

Solution of equation is (2, 1)
