Answer:
x = -5
Step-by-step explanation:
Using the given equation:
x - 2x - 5 = 3(x + 5)
Distribute: x - 2x -5 = 3x + 15
Combine like terms: -x - 5 = 3x + 15
Add 'x' to both sides: -x - 5 + x = 3x + 15 + x or -5 = 4x + 15
Subtract 15 from both sides: -5 - 15 = 4x + 15 - 15 or -20 = 4x
Divide both sides by 4: -20/4 = 4x/4 or x = -5
