Question

2x + 3y = 2 ; x -y = 1
2 2
by elimination method​

Answer 1

Answer:

$5x = 5 = x = 1$

$y = 0$

Answer 2

Answer:

2x + 3y = 2 ––—(1); x - y = 1––—(2)

; 3(x - y = 1)

; 3x - 3y = 3——(3)

Using elimination method

Adding eq.(1)in(3)

2x + 3y = 2

3x - 3y = 3

________

5x=5

x=5/5

x=1

using eq. x=1 in (1)

2x + 3y = 2

2(1) + 3y = 2

3y=2/2

y=1/3
