Решите уравнения; 1) 7(x- 3) = 2x + 4;

2) 2x - 7 = 5( x +1);

3) (x +4)*(-2) = (x +9)*3;

(x+7);

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

5) (10x-3)+(14x-4)=8-(1-22x); (3x+4)+(5x+5)=12-7x;

6) (2y - 1)/3 - (y - 7)/5 = 9; (2x + 6)/8 = 5;

7) (2x - 1)/5 - ( 6 - x)/3 = 4; (2 - a)/6 =1;

8) (x - 1)/2 = (x - 5)/3; = 0;

9) (x - 7)/6 = (x + 1)/2 - 3; (5x - 8)/1,2 - 2;

10) (21-x)/10-(5x-1)/12+(3x-3)/4 = 4 (3x-1)/5-(x-2)/2=0.​
