х = 112;

2) у + 17 = -27;

у = -27 - 17;

у = - 44;

3) z - 64 = -18;

z = -18 + 64;

z = 46;

4) -114 + a = 29;

a = 29 + 114;

a = 143;

5) x (-89) = -46;

x + 89 = -46;

x = -46 - 89;

b = -19 - 654;

b = -673;

8) 308 n = 309;

-n = 309 - 308;

-n = 1;

n = -1;

9) t (-445)=150;

t + 445 = 150;

t = 150 - 445;

t = -295;
