Question

1 1/3*(2x+4)=2 1/2*(3x=4)

3*(2-2x)+4*(x5)=4x=5

z góry DZIĘKUJE !

Answer 1

1 1/3 * ( 2x+ 4) = 2 1/2 * (3x =4) 

8/3x + 16/3 = 15/2 = 10

8/3x = 15/2 - 16/3 = 10

8/3x = 45/6 - 32/6 = 10

8/3x = 13/6 = 10

 

3* (2-2x) + 4* (x5) = 4x = 5

6 - 6x + 20x = 4x = 5

6 - 14x = 4x =5

-14x = 4x = 1
