Question

I need you to answer ASAP

Line R: 2x + 2y = 18
Line M: x + y = 9
Which statement is true about the solution to the set of equatic
It is (189)
It is (9, 18)
There are infinitely many solutions
There is no solution

Answer 1

infinitely many solutions

Explanation:

2x + 2y = 18

x + y = 9

multiply Line M equation by -2 to eliminate at least one variable:

2x + 2y = 18

-2x - 2y = -18

use elimination:

2x + 2y = 18

-2x - 2y = -18

__________

0 + 0 = 0

since this statement is true, there are infinitely many solutions.
