Question

Tìm x 3x( 4/3x + 1) - 4x(x - 2 ) = 10

Answer 1

4x² + 3x - 4x² + 8x - 10 = 0

11x - 10 = 0

x = 10/11

 

Answer 2

\(3x\left(\dfrac{4}{3}x+1\right)-4x\left(x-2\right)=10\)

\(\Leftrightarrow4x^2+3x-4x^2+8x=10\)

\(\Leftrightarrow x=\dfrac{10}{11}\)

Answer 3

\(3x\left(\dfrac{4}{3}x+1\right)-4x\left(x-2\right)=10\\ \Leftrightarrow4x^2+3x-4x^2+8x=10\\ \Leftrightarrow11x=10\Leftrightarrow x=\dfrac{10}{11}\)
