Encuentra el valor de la incógnita X

x - 6 =3

x + 32 =67

3x= 18

Answer 1

x - 6 = 3
x = 3 + 6
x = 9
Comprobamos:
x - 6 = 3
9 - 6 = 3
3 = 3

x + 32 = 67
x = 67 - 32
x =35
Comprobamos:
x + 32 = 67
35 + 32 = 67
67 = 67

3x = 18
x = 18 : 3
x = 6
Comprobamos:
3x = 18
3 . 6 = 18
18 = 18

Answer 2

x - 6 = 3
x = 3 + 6
x = 9

x + 32 = 67
x = 67 - 32
x = 35

3x = 18
x = 18/3
x = 6
