2x-3y = 8
2x = 8+3y
x = 8+3y/2 ( here you can put any value of y)
x= 8+3(2)/2. { taking y= 2&4. so,x=10& 7}
so,x= 7 and y = 2
x= 8+3(4)/2
so, x = 10 and y= 7
4x-6y-9= 0
4x-6y =9
4x= 9+6y
x= 9+6y/4. ( now putting the value of y)
As I had already done in 1st part.
similarly you have to do.

Answer:
Step-by-step explanation:
2x - 3y = 8
- 3y = - 2x + 8
y = (2/3)x - 8/3 , slope m = 2/3 , y-intercept b = - 8/3
4x - 6y - 9 = 0
- 6y = - 4x + 9
y = (4/6)x - 9/6
y = (2/3)x - 3/2 , slope m = 2/3 , y-intercept b = - 3/2
As we can see, slopes of both linear equations are the same, but y-intercepts are different this means lines are parallel and system of equations has no solution.
