Question

tìm x

(x+4).11=x.14

giúp mid vs mai mid phải nộp rồi

Answer 1

\(\left(x+4\right).11=x.14\\ \Leftrightarrow11x+44=14x\\ \Leftrightarrow11x-14x=-44\\ \Leftrightarrow-3x=-44\\ \Leftrightarrow x=\dfrac{44}{3}\)

Vậy \(x=\dfrac{44}{3}\)

Answer 2

\(\left(x+4\right).11=x.14\)

\(11x+44-14x=0\)

\(-3x-44=0\)

\(-3x=44\)

\(x=\dfrac{44}{3}\)

Answer 3

(x + 4).11 = x.14

11.(x + 4) = 14x

11x = 14x - 44

11x - 14x = 14x - 44 + 14x

-3x = -44

x = 44/3

Answer 4

Ta có: (x+4).11=x.14

\(\Leftrightarrow11x+44=14x\)

\(\Leftrightarrow44=14x-11x\)

\(\Leftrightarrow44=3x\)

\(\Leftrightarrow x=\dfrac{44}{3}\)

Vậy:............
