3(x-2)-5(x+2)=4
4(x+1)-2(4-3)(x+3)
5(x-2)-3+7-2(x-3)
6(x+3)-12+7-5(x+2)
4y-3(3y-5)=2y
3x-6-5x+10=4
3x-5x=4+6-10
-2x=-20/-2
x=2
4x+4-8+6+x+3
4x+x=8-4-6-3
5x=-8/5
x=-1,6
5x-10-3+7-2x+6
5x-2x=10+3-7-6
3x=0/3
x=0
4y-9y+15=2y
4y-9y-2y=-15
-11y=-15/-11
y=1
3x - 6 - 5x - 10 = 4
-2x = 4 + 16
-2x = 20
x = -10
hm a gdzie tu masz znak równości?
5(x-2)-3 = 7-2(x-3)
5x - 10 - 3 = 7 - 2x + 6
5x + 2x = 13 + 13
7x = 26
x = 26/7
x = 3 i 5/7
to samo, brakuje znaku równości
4y - 9y + 15 = 2y
-5y - 2y = -15
-7y = -15
y = 15/7
y = 2 i 1/7
