I need help on this please

c) infinite

Step-by-step explanation:

z - y = 12

-3z + 3y = -36

z - y = 12

add 12 to both sides of the equation

z - y + y = 12 + y

z = 12 + y

-3z + 3y = - 36

-3(12 + y) + 3y = -36

-36 -3y + 3y = -36

-36 = - 36

the answer is infinite solutions, because no matter what y and z are, -36 will always equal -36
