Question

How many solutions does the system have?

Answer 1

Answer: C. Infinite many solution

Step-by-step explanation:

#1 simplify the first equation: 20x-5y=5

since the GCF in it is 5, we factor out 5

                   4x-y=1

#2 compare the first and the second equation

                     $\left \{ {{4x-y=1} \atop {4x-y=1}} \right.$

we can see that both equation are same, which means they present the same line.

Thus, they overlap and they have infinite many solution

Answer 2

Answer:

Infinitely many solutions.

You basically have just one equation.

The top equation is the bottom equation times 5.
