-3:4(8x+12)=0 2(1:5x - 1:2 ) = 2:5 x - 1:2 5(x-5)=25( 1:5 x - 1 )
3:4 i 1:5 1:2 to są ułamiki prosze rozwiążcie to
-3/4(8x+12)=0 /* 4
-3 (8x + 12) = 0
-24x - 36 = 0
- 24x = 36 /: (-12)
2x = -3
x= -3/2
2(1/5x - 1/2 ) = 2/5 x - 1/2
2/5 x - 1 = 2/5 x - 1/2 /* 10
4x - 10 = 4x - 5
4x - 4x = -5 + 10
0 = 5
równanie jest sprzeczne
5(x-5)=25( 1/5 x - 1 )
5x - 25 = 5x - 25
5x - 5x = - 25 + 25
0 = 0
nieskończenie wiele rozwiązań
