Question

б)3х=-1 дробь 2 д)-5х=0 з)-4х= 8 дробь 25

Answer 1

3*x=-1/2

x=-1/2:3

x=-1/2"*1/3

x=-1/6

----------------------

3 *( -1/6)=-1/2

 

 

 

-5*x=0

x=0:(-5)

x=0

-----------------

-5 * 0 = 0

 

 

-4*x = 8/25

x = 8/25 : (-4)

x = - 8/25 * 4/4

x = - 2/25

-----------------------------

-4* (-2/25) = 8/25
