Question

Tìm X ;  3 x X + 2x X - 75 = 150 

Answer 1

3 x X + 2 x X - 75 = 150

5 x X = 150 + 75

5 x X = 225

      X = 225 : 5

      X = 45

Answer 2

3.x + 2.x - 75 = 150

=> 3.x + 2.x = 150 + 75 = 225.

=> 5.x = 225

=> x = 45.

Answer 3

\(3.x+2.x-75=150\)

\(5x=150+75\)

\(5x=225\)

\(x=225:5\)

\(x=45\)

Answer 4

\(\Rightarrow\)5\(x\)=75 \(\Rightarrow x=15\)

Answer 5

thanks nha 

Answer 6

3 x X + 2 x X - 75 = 150

3 x X + 2 x X        = 150 + 75 

3 x X + 2 x X        = 225

( 3 + 2 ) x X          = 225

   5        x X         = 225

                X         = 225 : 5 

                X         = 45

Vậy x = 45
