**Reiny**, Friday, July 9, 2010 at 8:58amtry to get either the x or the y coefficients to be alike

in this case I will get the y's to have a 15 in front

so multiply the first by 5 and the second by 3 to get

25r - 15s = 85

9r + 15s = 51

add them

34r = 136

r = 136/34 = 4

back in second, (or first)

3(4) + 5s = 17

12 + 5s = 17

5s = 5

s = 1
