Question

Check graphically whether the pair of equations
x + 3y = 6 1)
2x - 3y = 12 2)
is consistent. If so, solve them graphically.

Answer 1

x+3y = 6
1x + 3y - 6=0


comparing with a1x+b1y+c1=0

therefore a1=1,b1=negative 6



2x-3y-12=0
comparing with a2xb2y+c2=0

therefore a2=2,b2=negative 3,c2=negative 12


by the way all the letters apart from the question are supposed to be small anc at the bottom

Answer 2

$\huge\mathtt{\fbox{\red{Answer}}}$

x+3y = 6

1x + 3y - 6=0

comparing with a1x+b1y+c1=0

therefore a1=1,b1=negative 6

2x-3y-12=0

comparing with a2xb2y+c2=0

therefore a2=2,b2=negative 3,c2=negative 12
