mam do zrobienia pare przykładów
a oto one mam nadzieje że pomożecie:
daje naj
3 ( 2x -1 ) = 4 + ( x - 1)
6x - 3 = 4 + x - 1
6x = x + 6
5x = 6
x = 6/5
7(x-1) - 3(x+2) = 5
7x - 7 - 3x - 6 = 5
4 x = 18
x = 18/4 = 9/2 = 4.5
6 - (2x -3) = 3x - 3
6 - 2x + 3 = 3x - 3
9 = 5x - 3
12 = 5x
x = 12/5 = 2.4
6x - 4 = 5(x-3) + 1
6x - 4 = 5x - 15 + 1
x - 4 = - 14
x = -10
