Question

Which of the following systems of equations has infinitely many solutions?
A. 3x − 3y = 11; 6y = 9x − 22 B. 5y = -9x − 6; -27x + 15y = 15
C. 4x − 7y = 7; -14y = 8x − 14 D. -4x + 2 = 3y; 12y − 8 = -16x

Answer 3

C. 4x − 7y = 7; -14y = 8x − 14

Answer 4

write in the form a1x+b1y=c1 and
a2x+b2y=c2
\[if \frac{ a1 }{ a2 }=\frac{ b1 }{ b2 }=\frac{ c1 }{ c2 }\]
then there are infinite solutions
