Question

Gauss elsmination method
2x+3y=5,3x-y=2

Answer 1

Answer:

2x+3y=5 ----(1)

3x-y=2 -----(2)

lcm of 3 and 2 is 6

3(2x+3y=5)=6x+9y=15---(3)

2(3x-y=2)=6x-2y=4----(4)

sub(3)from(4)

11y=11

y=11/11

y=1

putting valve of y in eq (1)

2x+3y=5

2x+3(1)=5

3x=5-3

3x=2

x=2/3

Therefore, x=2/3 & y=1
