Question

tìm X :

( x- 25) :4=17 

x*5+x*2=7014

Answer 1

(x-25):4=17

x-25=17x4=68

x=68+25

x=93

x*5+x*2=7014

x*(5+2)=7014

x*7=7014

x=7014:7

x=1002

Answer 2

(x - 25) : 4 = 17

=> x - 25 = 68

=> x = 93

Vậy ....

x.5 + x . 2 = 7014

=> x( 5 + 2) = 7014

=> 7x = 7014

=> x = 1002

Answer 3

( x - 25 ) : 4 = 17

x - 25 = 17 x 4

x - 25 = 68

      x  = 68 + 25

      x  = 93

x*5 + x* 2 = 7014

x * ( 5 + 2 ) = 7014

x * 7 = 7014

     x = 7014 : 7

     x = 1002
