Answer 1

1.

(х-2)/4=1;  х-2=4;  х=6

2.

(3х+2)/5=4;  3х+2=20;  3х=18;  х=6

3.

х/2 + х/3 = 10;  3х+2х=60;  5х=60;  х=12

4.

х/3 - х/4 = 1;  4х-3х=12;  х=12

Answer 2

$\frac{x - 2}{4} = 1 \\ x - 2 = 4 \\ x = 4 + 2 \\ x = 6$

$\frac{3x + 2}{5} = 4 \\ 3x + 2 = 20 \\ 3x = 20 - 2 \\ 3x = 18 \\ x = 6$

$\frac{x}{2} + \frac{x}{3} = 10 \\ 3x + 2x = 60 \\ 5x = 60 \\ x = 12$

$\frac{x}{3} - \frac{x}{4} = 1 \\ 4x - 3x = 12 \\ x = 12$
