Question

Tìm x biết 96 - 3 (x + 1)  =42

Answer 1

96 - 3 ( x + 1 ) =42
3 ( x+1) = 42 - 96

3 ( x + 1 ) = 54

x + 1 = 54 : 3

x+1= 18

x = 18 - 1

x = 17

Answer 2

96-3(x+1)=42

3.(x+1)==96-42

x+1=54:3

x=17-1

x=16

Answer 3

96 - 3 ( x + 1 ) =42
3 ( x+1) = 42 - 96

3 ( x + 1 ) = 54

x + 1 = 54 : 3

x + 1 = 18

x = 18 - 1

x = 17

Answer 4

96 - 3(x + 1) = 42

3(x + 1) = 96 - 42

3(x + 1) = 54

x + 1 = 54 : 3

x + 1 = 18

x = 18 - 1

x = 17
