Odpowiedź:
a) - 3x+4 = -5x-1 / +5x
2x+4 = -1 / -4
2x = - 5 / :2
x = - 2,5
b) -(2x-1) = 4
-2x+1 = 4 / -1
-2x = 3 / :(-2)
x = -1,5
c) 3/4(2-3x) = -6
3/2-9/4x = -6 / -3/2
-9/4x = - 15/2 / :(-9/4)
[tex]x = \frac{3}{10} [/tex]
d) 2x-(x-3)(x-1) = 1
2x-(2x-x-3x+3) = 1
2x-2x+x+3x-3 = 1
4x-3 = 1 / +3
4x = 4 /:4
x = 1
e) 2x+3/5) = 2-x:3+x
2x+3/5 = 2-1/3x+x
2x+3/5 = 2+2/3x / - 2/3x
4/3x+3/5 = 2 / - 3/5
4/3x = 7/5 /:4/3
x = 21/20
[tex] x = 1 \frac{1}{20} [/tex]
Powinno być dobrze, za błędy z góry przepraszam
