Zadania na poziomie klas 6 co dziwne ponieważ z matmy jestem naprawde dobra z tym nie moge sobie dać rady !! POMOCY

Answer 1

1. 2x+(4x+3)4x-10+12x-x+x-14+16y-5x=3(8x-10y)-5+y :(1,5-9)+4x+12
(2) - kwadrat
2x+16x(2)+12x-10+12x-14+16y-5x=24x-30y-5+y/1,5-y/9+4x+12
21x+16x(2)-24+16y=28x+7-30y+y/1,5-y/9
21x+16(2)+16y-28x+30y-y/1,5+y/9=24+7
-7x+16x(2)+46y-5y/9=31

2. 4[-x+5]-2x+13-8x-1x-3+5y=9x-3(5-2)8[-6x+4]x3-1y+13y
-4x+20-2x+13-8x-x-3+5y=9x-15+6-38x+32+3-y+13y
-15x+30+5y=-29x-6+12y
-15x+5y+29x-12y=-30-6
14x-7y=-36

3.5x-(-8)+12y-8x-2(5x-7)-6(4-1x)=2x+15-x(6-16)+1,7
5x+8+12y-8x-10x+14-24+6x=2x+15-6x+16x+1,7
-7x-2+12y=12x+16,7
-7x+12y-12x=2+16,7
-19x+12y=18,7
