Test 2 Section 3 Number 20 please!

When a system of linear equations has an infinite number of solutions, what that really means is that both linear equations *produce the same line*!

Because we know the equations are equivalent, let’s multiply the top equation by 5 on both sides so that we have both equations equaling 60.

Since the equations are equivalent, we know that the corresponding coefficients are equal: and . From that, we can conclude that , which of course simplifies to .
