Oblicz :
2x + 5 - 3x - 12 ( 3x-12 podzielić przez 3) =
((12x + 16) :4) - ((10x + 15) : 5 ) =
((9 - 6x) : 3) - (( 21 - 14x) : 7) =
(( 4(x-1 ) : 2 - 3) - razy ((10x - 50) : 5) =
WAŻNE, PROSZĘ POMÓŻCIE !!!

2x+5-x-4=x+1
(3x+4)-(2x+3)=3x+4-2x-3=x+1
(3-2x)-(3-2x)=3-2x-3+2x=0
(2x-2-3)*(2x-10)=(2x-5)(2x-10)=4x²-20x-10x+50=4x²-30x+50
