good, then how far have you gotten :)
OpenStudy (amistre64):
2w - 5z = 13 ; *-3
6w + 3z = 10
-6w +15z = -39
6w + 3z = 10
---------------
18z = -29
z = -29/18 and simplify as wanted
OpenStudy (amistre64):
2w - 5z = 13
6w + 3z = 10 ; *5/3
2w - 5z = 13(3)/3
10w +5z = 50/3
---------------
12w = 89/3
w = 89/36 ... and simplify
OpenStudy (anonymous):
thats fast :)
OpenStudy (amistre64):
