a)
[tex] 2(x - 6) = 4(x - 2) \\ 2x - 12 = 4x - 8 \\ - 2x = 4 \\ x = - 2[/tex]
b)
[tex]10x + 60 = 14x - 56 \\ - 4x = - 116 \\ x = 29[/tex]
c)
[tex]4x - 24 = 8x - 4 \\ - 4x = 20 \\ x = - 5[/tex]
d)
[tex]3x + 30 = 2x + 18 \\ x = - 12[/tex]
e)
[tex]5x + 200 = 32 - 4x \\ 9x = - 168 \\ x = - \frac{168}{9} \\ x = - 18 \frac{6}{9} \\ x = - 18 \frac{2}{3} [/tex]
f)
[tex]8x - 16 = 9 - 3x \\ 11x = 25 \\ x = 2 \frac{3}{25} [/tex]
g)
[tex]14x - 4 = 18x - 3 \\ - 4x = 1 \\ x = - \frac{1}{4} [/tex]
h)
[tex]24 - 6x = 20 + 8x \\ - 14x = - 4 \\ x = \frac{4}{14} \\ x = \frac{2}{7} [/tex]
i)
[tex]32x - 16 = 6x - 9 \\ 26x = 7 \\ x = \frac{7}{26} [/tex]
j)
[tex]14 + 21x = 6x - 12 \\ 15x = - 26 \\ x = - \frac{26}{15} \\ x = - 1 \frac{11}{15} [/tex]
k)
[tex]16x - 32 = 6x - 54 \\ 10x = - 22 \\ x = - 2 \frac{1}{5} [/tex]
proszę o naj ;)
