Question

5 - ( 3x + 5 ) = 18 - ( -2x + 3 ) giups mk với nhé mk đang cần gấp!!!

Answer 1

\(5-\left(3x+5\right)=18-\left(-2x+3\right)\)

\(5-3x-5=18+2x-3\)

\(-3x-2x=18-3-5+5\)

\(-5x=15\)

\(x=-3\)

Answer 2

\(5-\left(3x+5\right)=18-\left(-2x+3\right)\)

\(\Leftrightarrow5-3x-5=18+2x-3\)

\(\Leftrightarrow-3x=15+2x\)

\(\Leftrightarrow-2x-3x=15\)

\(\Leftrightarrow-5x=15\)

\(\Leftrightarrow x=-3\)

Answer 3

\(5-\left(3x+5\right)=18-\left(-2x+3\right)\)

     \(5-3x-5=18+2x-3\)

                  \(-3x=15+2x\)

     \(-3x-2x=15\)

                \(-5x=15\)

                       \(x=-3\)

Answer 4

          5 - (3x+5) = 18 - (-2x+3)

            5 - 3x -5 =18 + 2x - 3

                -3x = 15 + 2x

           -3x  - 2x =15

             -5x =15

               x = -3  

Answer 5

Trả lời:

\(5-\left(3x+5\right)=18-\left(-2x+3\right)\)

\(\Leftrightarrow5-3x-5=18+2x-3\)

\(\Leftrightarrow-3x-2x=15\)

\(\Leftrightarrow-5x=15\)

\(\Leftrightarrow x=-3\)

Vậy\(x=-3\)

Hok tốt!
