Question

                помогите решить уравнения!

 1)   1/4 + х + 3/4 = 11/16 +7/8

 

2) (3/5 + х) - (17/30 + 1/5) = 1/30 + 1/6 - 1/10

    

Answer 1

1/4 + х + 3/4 = 11/16 +7/8

1/4 + х + 3/4 = 25/16

(1/4 + 3/4 =1)

х = 25/16 - 1 = 24/16

   

 

 

(3/5 + х) - (17/30 + 1/5) = 1/30 + 1/6 - 1/10

 (3/5 + х) - (17/30 + 1/5)  =1/10

(17/30 + 1/5 = 23/30)

3/5 + х = 23/30 х = 23/30 - 3/5 = 1/6
