Answer 1

1.

24*x-3/8=24*x+3/12

3x-9=2x+6

3x-2x=6+9

x=15

2.

3*(3(x-2))/3=3*(4(x+3))/3

3x-6=4x-12

3x-4x=-12+6

-x=-6/*(-1)

x=6

3.

12*(5(x-2))/3=12*(5x-20)/4

4*(5x-10)=15x-60

20x-40=15x-60

20x-15x=-60+40

5x=-60/:5

x=-12

Answer 2

1)

(x-3)*12=(x+3)*8

12x-36=8x+24

12x-8x=24+36

4x=60  :4

x=15

2)

[3(x-2)]*3=[4(x+3)]*3

(3x-6)*3=(4x+12)*3

9x-18=12x+36

9x-12x=36+18

-3x=54 :(-3)

x=-18

3)

[5(x-2)]*4=(5x-20)*3

(5x-10)*4=15x-60

20x-40=15x-60

20x-15x=-60+40

5x=-20 :5

x=-4
