Question

Solutia ecuatiei: 2x+1/6 : 5/2 = x-1/3 ?

Answer 1

Explicație pas cu pas:

2x+1/6• 5/2=x-1

2x+1/15=x-1

2x-x= -1/15-1 aducem la acelasi numitor

x= -1/15-15/15

x= -16/15

Answer 2

Răspuns:

Explicație pas cu pas:

( 2x+1)/6   : 5/2 = ( x - 1 )/3

[ ( 2x+1)/6]  × ( 2/5 ) = ( x - 1 ) /3

( 2x+1)/(3×5) = (x-1)/3

15( x - 1 ) = 3 ( 2 x + 1 ) l  : 3

5(x - 1 ) = 2 x + 1

5 x - 5 = 2 x + 1

5 x - 2 x = 1 + 5

3 x = 6

x = 6 : 3

x = 2
