Question

Which of the following systems of equations has infinitely many solutions? Answer

3x − 3y = 11; 6y = 9x − 22

5y = -9x − 6; -27x + 15y = 15

4x − 7y = 7; -14y = 8x − 14

-4x + 2 = 3y; 12y − 8 = -16x
please help me

Answer 1

-4x + 2 = 3y; 12y − 8 = -16x

Answer 2

the equation with\[\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\]will have infinite solution
