Answer:
0 = 0
Step-by-step explanation:
2+5x−7=3x−9+2x
Step 1: Simplify both sides of the equation.
−2+5x−7=3x−9+2x
−2+5x+−7=3x+−9+2x
(5x)+(−2+−7)=(3x+2x)+(−9)(Combine Like Terms)
5x+−9=5x+−9
5x−9=5x−9
Step 2: Subtract 5x from both sides.
5x−9−5x=5x−9−5x
−9=−9
Step 3: Add 9 to both sides.
−9+9=−9+9
0=0
