Question

(2x + 1).5 = 35

Answer 1

\(\left(2x+1\right).5=35\)

\(\Rightarrow2x+1=7\)

\(\Rightarrow2x+6\Rightarrow x=3\)

Answer 2

\(\Leftrightarrow2x+1=7\Leftrightarrow x=3\)

Answer 3

\((2x+1).5=35\\<=>2x+1=7\\<=>2x=6\\<=>x=3\)

Answer 4

2x+1=35 : 5

2x+1=7

2x=6 

X=6 : 2

x=3

Answer 5

\(\left(2x+1\right).5=35\)

\(2x+1=35:5\)

\(2x+1=7\)

\(2x=7-1\)

\(2x=6\)

\(x=6:2\)

\(\Rightarrow x=3\)

Answer 6

(2x + 1) . 5 = 35

(2x + 1 ) = 35 : 5 

(2x + 1) = 7

2x = 7-1 

2x = 6

x = 6 : 2 = 3

Vây x =3
