Question

3x-2y+2 0,3x-2y+6 0
​

Answer 1

Step-by-step explanation:

3x-2y+2=0

3x-2y=-2...............(1)

3x-2y+6=0

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

subtracting equation 2 by 1.

3x-2y=-2

3x-2y=-6

----------------

(-) (+) (+)

-----------------

0 0 =-8

subtuting x=-8 in equation (1)

3x-2y=-2

3 (-8)-2y=-2

-24 -2y= -2

-2y=-2+24

2y=22

y=11

subtuting y=11 in equation (1)

3x-2y=-2

3x-2×11=-2

3x-22=-2

3x=-2+22

3x=20

x=6.67

(x,y)=(6.67, 11)
