Oblicz czy co z tym zrob
2a + 3ab - 4 - 5a + - 2ab =
-(5x - 18y - 3 )
3(4a - x) =
-4(3a -2x -17)
(9x - 12y + 15)/3
Też z tym coś zrób : 3 * x + 2 dla x=-2
a*(5-2*b) dla a=2
Z góry dziekuje :*

2a+3ab-4-5a+ -2ab=ab-3b-4
-(5x-18y-3)=-5x+18y+3
3(4a-x)=12a-3x
-4(3a-2x-17)=-12a+8x+68
(9x-12y+15)/3=3x-4y+5
3*x+2 dla x=-2
-6+2=-4
a*(5-2*b) dla a=2
2(5-4)=2*1=2
2a + 3ab - 4 - 5a + - 2ab = -3a + 1ab -4
-(5x - 18y - 3 ) = -5x + 18y + 3
3(4a - x) = 12a - 3x
-4(3a -2x -17) = -12a +8x + 68
(9x - 12y + 15)/3 = 3x - 4y + 5
3 * x + 2 dla x=-2 ... = -6 + 2 = -4
a*(5-2*b) dla a=2 .... = 10 - 4b
