Respuesta :
- 4 + 9 × x = 58
- 9x + 4 = 58
- 9x = 58 - 4 = 54
- 9x = 58
divide 58 by 9 ( 58 ÷ 9 = 6 )
- x = 6
now let's find the number ,
- x × ( 9 + 4 ) = 58
since x = 6 ,
- 6 × ( 9 + 4 ) = 58
thus the number is 58
divide 58 by 9 ( 58 ÷ 9 = 6 )
now let's find the number ,
since x = 6 ,
thus the number is 58
