Kto rozwiąże ??? tylko dobrze prosze :) 3(5x+2)+9(12x+1)=51 3x(5-2)-2x(3+2)=38
3(5x+2)+9(12x+1)=51
15x+6+108x+9=51
15x+108x=51-9-6
123x=36 /:123
3x(5-2)-2x(3+2)=38
15x-6x-6x-4x=38
-x=38 /:(-1)
x=-38
15x + 6 + 108x + 9 = 51
123x = 36 | : 123
x = 36/123
x = 12/41
15x - 6x -6x - 4x = 38
-x = 38
x = -38
