Odpowiedź:
a)
[tex]\frac{5x-3}{4}+3=2x[/tex] |*4
5x-3+12=8x
5x-8x = -9
-3x = -9 |:(-3)
x = 3
b)
[tex]x-\frac{2x+3}{5} =3[/tex] |*5
5x-2x-3 = 15
3x = 15+3
3x = 18 |:3
x = 6
c)
[tex]4-\frac{x}{4} =2x-\frac{1}{2}[/tex] |*4
16-x = 8x - 2
-x -8x = -2-16
-9x = -18 |:(-9)
x = 2
d)
[tex]\frac{2x}{3} +4=\frac{x+2}{3}|*3[/tex] |*3
2x + 12 = x+2
2x-x = 2-12
x = -10
e)
[tex]\frac{3x-2}{5}-2=\frac{x}{5}[/tex] |*5
3x-2-10=5
3x-12=5
3x = 5+12
3x = 17 |:3
[tex]x=5\frac{2}{3}[/tex]
