помогите пожалуйсто решить уровнения

(45-x)*3=93 
(x-13):7=2  
72:(х+12)=4  
9х+5=41   
(Х+4)+(Х+5+4)=19    

Answer 1

(45-x)*3=93           (x-13) : 7 = 2        9x+5=41          (x+4)+(x+5+4)=19
45-x=93 : 3            x-13=2*7             9x=41-5           x+4+x+9=19
45-x=31                 x-13=14              9x=36              2x=19-13
x=45-31                 x=14+13             x=36 : 9           2x=6
x=14                     x=27                   x=4                  x=3
