Question

Chapter = Linnear simulation equation. Please answer it fast whose answer is correct I give it brainlieast answer​

Answer 1

Answer:

2x+3y-7=0

3x+2y

Step-by-step explanation:

2x+3y=7 --------------------------------------equation 1

3x+2y=-28 -----------------------------------equation 2

Adding equation 1 + equation 2

2x+3y=7__________________1

3x+2y=-28 __________________2

____________

5x+5y=35

Dividing 5 by both sides

x+y=7 --------------------------------------equestion 3

Subtracting equation 1+ equation 2

2x+3y=7__________________1

3x+2y=-28 __________________2

- -. +

_________

-1x+1y=35___________equation 4

Multiplying equation 3 by 1

1x+1y=7 _____________5

Adding equation 5 + equation 4

-1x+1y=35

1x1y=7

________

2y. =28

y= 28

_

2

y=14

Put y = 14 in equation 5

1x+1y=7

1x+1×14= 7

1x+14=7

1x=7-14

1x= -7

x=-7

-

1

x=-7

(x,y) ; ( -7, 14 )
