Question

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.

Answer 1

please help

Answer 2

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

Answer 3

i dont know

Answer 4

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

Answer 5

2

Answer 6

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?

Answer 7

i dont know

Answer 8

It means that they're the same line.

Answer 9

I'm willing to help if you're at least willing to try.

Answer 10

ok

Answer 11

but i don't get what the answer will be

Answer 12

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

Answer 13

just 1 solution

Answer 14

Nope. Try again.

Answer 15

no solution

Answer 16

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