Question

Va rog e fff urgent dau coroana mate cls 5: Gasiti solutiile naturale ale ecuatiilor: a)57(2-11x)=57; b) 29(4-12x)=203​

Answer 1

a) 57 ( 2 - 11 x ) = 57

2 - 11 x = 57 : 57

2 - 11 x = 1

11 x = 2 - 1

11 x = 1

x = 1 : 11

x = 0, ( 09 )

b) 29 ( 4 - 12 x ) = 208

4 - 12 x = 208 : 29

4 - 12 x = 7, 17

12 x = 4 - 7, 17

12 x = - 3 , 17

x = ( - 3, 17 ) : 12

x = - 0, 2641 ( 6 )
