Answer 2

Answer:

By elimination method

Step-by-step explanation:

1.

2x+3y=8 ......1

x+2y=5...........2

Multiply eq. 2 by ×2

=. 2x+3y=8........3

2x+4y=10.......4

By subtracting equation 3 by 4 we get

y=2,

By substituting the value of y in equation 1

we get,

2x+3×2=8

x=1

Ans is x,y

2,1

2.

3x+4y=25..............1

5x -6y=-9.................2

Multiply eq . 1 by 3 and eq 2 by 2

Therefore ,we get

9x+12y=75..........3

10x-12y=-18..........4

now by adding equation 3 and 4

we get,

x=3

Substitute the value of x in eq 1

We get

3×3+4y=25

y=4
