If 2 equations have the same y-intercept, they are overlapping, which means they have infinite solutions. So there is no way that 2 equations with the same y-intercept will have no solution. Thus your answer is: C)Never.
The answer is
.
Let's solve your equation step-by-step.
2b+3b=3
Step 1: Simplify both sides of the equation.
2b+3b=3
(2b+3b)=3(Combine Like Terms)
5b=3
5b=3
Step 2: Divide both sides by 5.
5b/5=3/5
So, the answer is
.
For this case we must solve a system of two equations with two unknowns, given by "x" and "y".
We have:

We multiply (2) by -1:

We add (1) and (3):

Clearing x:

We substitute
in (2)

Thus, the solution of the system is 
Answer:
The solution of the system is
