Question

6x-4y=-2;8x-3y=-2 by substitution method

Answer 1

Step-by-step explanation:

6x-4y= -2

dividing by 2 on both sides

3x-2y= -1

-2y= -1+3x

-2y= 3x-1

y= (1-3x)/2

substitute the value of y in the second equation

8x - 3[(1-3x)/2]= -2

8x-3/2+9x/2= -2

8x+9x/2= -2+3/2

25x/2= (-4+3)/2

25x= -1

X= -1/25

y= [1-3(-1/25)]\2

y= (1+3/25)/2

y= 28/50
