Question

Prosze o rozwiązanie tych przykładów :

5/9x-4+4/3x=-2(3x-3)
-3(x+2)-2(2x-3)=3x-6
-x-8+x=-2x-4

Answer 1

5/9x +4/3x - 6x = 6 + 4
-37/9 = 10
x= -4 i 1/9

-3x - 6 - 4x + 6= 3x - 6
-3x - 4x - 3x = -6 + 6 - 6
-10x = -6
x=6/10 = 3/5

-x +x +2x = -4 + 8
2x = 4
x= 2

Answer 2

5/9x-4+4/3x = -2(3x-3)
5/9x+12/9x-4 = -6x+6
17/9x-4 = -6x+6
17/9x+6x = 6+4
1i8/9x+6x = 10
7i8/9x = 10 |:7i8/9
x = 1i19/71

-3(x+2)-2(2x-3) = 3x-6
-3x-6-4x+6 = 3x-6
-7x = 3x-6
6 = 3x+7x
10x = 6 |:10
x = 0,6

-x-8+x = -2x-4
-8 = -2x-4
2x = -4+8
2x = 4 |:2
x = 2

Answer 3

5/9x-4+4/3x=-2(3x-3)
5/9x-4+4/3x=-6x+6
5/9x+4/3x+6x=6+4
7⁸/₉x=10
x=1¹⁹/₇₁


-3(x+2)-2(2x-3)=3x-6
-3x-6-4x+6=3x-6
-3x-4x-3x=-6+6-6
-10x=-6
x=⅗


-x-8+x=-2x-4
-x+x+2x=-4+8
2x=4
x=2
