Solve the following system using any method.
5x  2y = 16
3x + 5y = 22
(7, 2)
(4,2)
(4, 6)
No solution. The system is inconsistent.
Infinite number of solutions. The system is dependent.

5x  2y = 16 3x + 5y = 22 OK for this two ways, well actually 3. First, put in x and y into both equations and see if it works. Do you know elimination?

Well... eliminate either x or y by making the values of them in both equations the same. So for this one, I will eliminate x. The LCM of 5 and 3 is 15. In both equations we want 15x. Multiply the first equation by 3, and the second by 5 to get: 15x  6y = 48 15x + 25y = 110 Now Subtract one from the other: 15x  6y  (15x + 25y) = 48 (110) 31y = 62 y = 2 Now substitute y = 2 into any of the first equations. I'll choose eq 1 3x + 5(2) = 22 3x  10 = 22 3x = 12 x = 4 And there you have it

Your welcome. Do you know the other method? Substitution?

Or you could use matrices...
