Question

tìm x 

3(2x-3)+2(2-x)=-3

Answer 1

\(3\left(2x-3\right)+2\left(2-x\right)=3\)

=> 6x - 9 + 4 - 2x = 3

=> 4x - 5 = 3

=> 4x = 8

=> x = 2

Answer 2

\(3\left(2x-3\right)+2\left(2-x\right)=-3\)

\(\Leftrightarrow6x-9+4-2x=-3\)

\(\Leftrightarrow4x=2\)

hay \(x=\dfrac{1}{2}\)

Answer 3

    3.( 2x - 3) + 2(2 - x) = -3

⇒ 6x - 9 + 4 - 2x = -3

⇒ 4x - 5 = -3

⇒ 4x = 2

⇒ x = \(\dfrac{1}{2}\)

Answer 4

     \(3\left(2x-3\right)+2\left(2-x\right)=-3\)

⇔          \(6x-9+4-2x=-3\)

⇔                   \(4x-9+4=-3\)

⇔                          \(4x-5=-3\)

⇔                                \(4x=2\)

⇔                                  \(x=\dfrac{1}{2}\)
