Two lines, R and M, are represented by the following equations: Line R: 2x + 2y = 18 Line M: x + y = 9 Which statement is true about the solution to the set of equations? It is (18, 9). It is (9, 18). There are infinitely many solutions. There is no solution.

Okay, let's try and solve the system of equations by using elimination. How many times does the second equation go in the first?

Put the equation side by side one another. What do you have to multiply with x to turn into 2x? What do you have to multiply with y to get 2y and what do you have to multiply with 9 to get 18? 2x + 2y = 18 x + y = 9

2

Multiply the second equation by 2 then. 2(x + y = 9) It'll equal the first equation. If the second equation and the first equation are equal, what does that mean?

It means that they're the same line.

What do same lines have? Infinite solutions, no solution, or just one solution?
anonymous
  • anonymous
just 1 solution

Nope. Try again.

No. They have infinite solutions. Every single point is the same.
