6(х-3)+2(х+2)=1.5(х-1)-4(х-2)=103(х-9)+5(х-4)=17(х-9)-(3х+1)=9

Решим уравнения:

1) 6 * (х - 3) + 2 * (х + 2) = 1; 

6 * x - 18 + 2 * x + 4 = 1; 

8 * x - 14 = 1; 

8 * x = 1 + 14; 

8 * x = 15; 

x = 15/8; 

2) 5 * (х - 1) - 4 * (х - 2) = 10; 

5 * x - 5 * 1 - 4 * x + 4 * 2 = 10; 

5 * x - 5 - 4 * x + 8 = 10; 

5 * x - 4 * x + 3 = 10; 

x + 3 = 10; 

x = 10 - 3; 

x = 7; 

3) 3 * (х - 9) + 5 * (х - 4) = 17; 

3 * x - 3 * 9 + 5 * x - 5 * 4 = 17; 

3 * x - 27 + 5 * x - 20 = 17; 

8 * x - 47 = 17; 

8 * x = 17 + 47; 

8 * x = 64; 

x = 64/8; 

x = 8; 

4) (х - 9) - (3 * х + 1) = 9;  

x - 9 - 3 * x - 1 = 9; 

-2 * x - 10 = 9; 

-2 * x = 9 + 10; 

-2 * x = 19; 

x = -19/2; 

x = -9.5.
