Rozwiąż równania: a) 3x-1=5x b)y-3=9-y c)1/2z +6=z-1 na dzisiaj!!!
a) 3x-1=5x
3x - 5x = 1
-2x = 1 /:(-2)
x = -0,5
b) y-3=9-y
y + y = 9 + 3
2y = 12 /:2
y = 6
c) 1/2z +6=z-1
0,5z - z = -1 - 6
-0,5z = -7 /:(-0,5)
z = 14
3x-5x=1
-2x=1 /:(-2)
x=-1/2
b)y-3=9-y
y+y=9+3
2y=12 /:2
y=6
c)1/2z +6=z-1
1/2z-z=-1-6
-1/2z=-7 /*2
-z=-14 /*(-1)
