a)
[tex]\frac{4x - 1}{3} = 5[/tex]
4x - 1 = 5 * 4
4x - 1 = 20
4x = 19
x = 4,75
b)
[tex]\frac{2 - 3x}{4} = 1[/tex]
2 - 3x = 1 * 4
2 - 3x = 4
- 3x = 2
[tex]x = -\frac{2}{3}[/tex]
c)
[tex]\frac{6x + 1}{5} = x[/tex]
6x + 1 = 5x
1 = - x
x = - 1
d)
[tex]3 - x = \frac{2x - 3}{2}[/tex]
(3 - x) * 2 = 2x - 3
6 - 2x = 2x - 3
- 4x = - 9
x = 2,25
e)
[tex]\frac{2x - 1}{2}= \frac{1 - x}{4}[/tex]
(2x - 1) * 4 = 2 * (1 - x)
8x - 4 = 2 - 2x
6x = 6
x = 1
f)
[tex]\frac{x - 3}{2}= \frac{x - 2}{3}[/tex]
(x - 3) * 3 = 2 * (x - 2)
3x - 9 = 2x - 4
x = 5
