Answer

-9

Step 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

Step 2: Subtract 44 from both sides.

x+4−4=−5−4x + 4 - 4 = -5 - 4

Simplify.

x=−9x = -9

Final answer: x=−9x = -9

-9
