Question

(2+2x).3 5/6=46

Answer 1

\(\left(2+2x\right)\cdot3\dfrac{5}{6}=46\)

\(\left(2+2x\right)\cdot\dfrac{23}{6}=46\)

\(2+2x=46:\dfrac{23}{6}\)

\(2+2x=46\cdot\dfrac{6}{23}\)

\(2+2x=12\)

\(2x=12-2\)

\(2x=10\)

\(x=10:2\)

\(x=5\)

Vậy \(x=5\).

Answer 2

(2+2x) . 3 5/6 = 46

=> (2+2x) . 23 = 46

=> 2 + 2x = 46 : 23

=> 2 + 2x = 2

=> 2x = 0

=>x = 0

Answer 3

( 2 + 2x ) . \(3\dfrac{5}{6}\)= 46

( 2 + 2x ) . \(\dfrac{23}{6}\)=46

2 + 2x = 46 : \(\dfrac{23}{6}\)

2+ 2x = 12

2x = 10

x = 5
