Treść zadania

Rozwiąż równania:
3x – 4 = x – 5
-20x + 2 = -30x + 12
-3 (x – 1) = 5 (x + 2)
3 – (x – 1) = -2( x + 1)
2(3 – 4x) -4(x + 1) = -x -7(x – 2)
3 – (4 – x) +5(1 – 2x) – x – 5 = 0
3 – x(3 – 2x) -2x² = 5 – x
3x – 2x(2x + 1) = -x (4x + 2)
1-1/4 x=5/6 x
1/10 x-2=1/100(x-199)
1/3 (x-1)= -1/6(1-x)
1/7 x+ 1/8 x= -1
1/12 x- 1/8 x=1
1/3 x- 1/2 x= 1/6+ x
1-0,02x=0,01+0,04x
1+ 3/4 (2x+1)= -1/3 (1 – 2x)
1/2 (3x-5)- 1/4 (x+1)= -1
(x-1)/2+ (x+2)/3=1
1/2 (x-3)-1/3 (x-2)+ x=2 2/3
(2(x-1))/3- (3x+1 )/2 + 2 = 0
0= - (2x-1)/3+ 3(2x+1)- 9x/2
3⌊5(-x+1)- 2⌋=4
