Answer

-9

Step-by-step solution

2 steps

  1. Start with the given equation.

    3x+4=2x−53x + 4 = 2x - 5

    Subtract 2x2x from both sides.

    3x−2x+4=2x−2x−53x - 2x + 4 = 2x - 2x - 5

    Simplify.

    x+4=−5x + 4 = -5

  2. Subtract 4 from both sides.

    x+4−4=−5−4x + 4 - 4 = -5 - 4

    Simplify.

    x=−9x = -9

    Final answer: x=−9x = -9

    -9
