Find out whether the lines represent the following pairs of linear equations

intersect at a point or parallel or coincide.

a) 3x - 4y =3 and X- 2y =2

b) X - 3y =7 and 3x - 9y =21

c) -3x +4y =5 and 9/2 x-6y +15/2 = 0


PLEASE ANSWER IT FAST NO SPAM PLEASE ​

Answer 1

Step-by-step explanation:

a)3x-4y+x-2y=2+3

3x+x-4y-2y=5

4x-2y=5

b)x+3y+3x-9y=21+7

x+3x+3y-9y=28

4x+(-3y)=28

4x-3y=28
