To solve the system of equations, we can use the method of substitution or elimination. Let's use the elimination method.First, let's eliminate the variable y by multiplying the first equation by 2 and adding it to the second equation:
Adding these two equations, we get:
Simplifying, we have:
Now, let's substitute this value of z into the third equation:
Simplifying, we get:
Now, let's solve for y in terms of x:
So, the solution to the system of equations is:
Therefore, the correct choice is B. There are infinitely many solutions. The solutions are
