Question

x x 6 + x x 3 = 142 - 97

Answer 1

x x 6 + x x 3 = 142 - 97

x x ( 6+3)      = 45

x  x   9        =  45

x                 = 45 : 9

x                 =5

Answer 2

\(x . 6 + x . 3 = 142 - 97\)

\(x . 6 + x . 3 = 45\)

\(x.(6+3)=45\)

\(x.9=45\)

\(x=45:9=5\)

Answer 3

ez mà hand đâu

 

Answer 4

`x xx 9 = 45`

`=> x = 45/9`

`=> x = 5`
