f)2t-(3t+1)=6
aha chodzi o to zeby rozwiązac rownania
a) -3x - 2x= -10
-5x=-10 |:(-5)
x=2
b) 2x+x=7+2
3x=9 |:3
x=3
c)10-4=-2x
6=-2x |:(-2)
x=-3
d) -2x+1=4
-2x=3 |:(-2)
x= -1,5
e) 2x+2=x
x=-2
f)2t-3t-1=6
-t=7 :(-1)
t= -7
a) -3x=2x-10
5x=-10 /5
b) 2x-2=7-x
3x=9 /3
d)-(2x-1)=4
-2x+1=4
-2x=3 / (-2)
x=-3/2
c)10=4-2x
6=-2x
2x+2=x
2t(-3t-1)=6
-6t-2t=6
-8t=6 /(-8)
t= - 4/3
