c koi la reponse de ca svp : x+15=26 ,, x-15,7=108 ,,, 105-x=95 ,,,, 3x=36

x+15=26
x = 26-15
x = 11


x-15,7=108
x = 108+15.7
x =123.7

105-x=95 
-x =95 -105
-x =-10
x =10

 3x=36
x = 36/3
x =12

x + 15 = 26
x + 15 - 15 = 26 - 15
x = 26 - 15
x = 11

x - 15.7 = 108
x - 15.7 + 15.7 = 108 + 15.7
x = 108 + 15.7
x =  123.7

105 - x = 95
105 - x + x = 95 + x
105 - 95 = 95 + x - 95
x = 105 - 95
x = 10

3x = 36
3x/3 = 36/3
x = 36/3
x = 12
