5x-3 * (2-x) = 3x+4

0.6x-5 * (1-2x) = 8x+1

4x-5 * (1-2x) = 8x+1

5x-3 * (2-x) = 3x+4

5x-6+3x=3x+4

5x+3x-3x=4+6

5x=10

x=10/5

x=2

Проверка: 5*2-3 (2-2) = 3*2+4

10=0=6+4

10=10

0.6x-5 * (1-2x) = 8x+1

0.6x-5+10x=8x+1

0.6x+10x-8x=1+5

2.6x=6

x=6/2.6

x=6: 2 6/10 = 60/26

x=30/13

x = 2 4/13

Проверка: 0.6*6/2.6-5 (1-2*6/2.6) = 8*6/2.6+1

19.461538=19.461538

4x-5 * (1-2x) = 8x+1

4x-5+10x=8x+1

4x+10x-8x=1+5

6x=6

x=6/6

x=1

Проверка: 4*'-5 (1-2*1) = 8*1+1

9=9
