If you would like to know what is true about the solution of the set of equations, you can calculate this using the following steps:
2x + 2y = 18
x + y = 9 /*2
______________
2x + 2y = 18
2x + 2y = 18
______________
2x + 2y = 2x + 2y
18 = 18
0 = 0
The correct result would be infinitely many solutions.
2x + 2y = 18
x + y = 9 /*2
______________
2x + 2y = 18
2x + 2y = 18
______________
2x + 2y = 2x + 2y
18 = 18
0 = 0
The correct result would be infinitely many solutions.
There are infinitely many solutions, because many numbers could be x and y.
