a)2(x+m)=m-4x+5 wyznacz m
2x+2m=m-4x+5
2m-m=-4x+5-2x
m=-6x+5
b) x-3(n+2x)=4n+2x wyznacz x
x-3n-6x=4n+2x
-5x-2x=4n+3n
-7x=7n/:-7
x=-n
c)3px-b+c=7px+4c wyznacz x
3px-7px=4c-c+b
-4px=3c+b/-4p
x=(3c+b)/-4p
d) c/t=a/x wyznacz a
ta=cx/:t
a=cx/t
e) d/4x=a/b wyznacz x
4ax=bd/:4a
x=bd/4a
a)2x+2m=m-4x+5
2m-m=-4x-2x+5
m=-6x+5
b)x-3n-6x=4n+2x
x-6x-2x=4n+3n
-7x=7n
x=-n
c)3px-b+c=7px+4c /: p
3x-b+c=7x+4c
3x-7x=b+3c
-4x=b+3c
x= -(b+3c)/-4
