To solve the equation −4x=1+x, let's follow these steps:
- Step 1: Subtract x from both sides of the equation to start isolating x. This gives:
−4x−x=1+x−x.
- Step 2: Simplify the equation. Combine like terms:
−5x=1.
- Step 3: Divide both sides by −5 to solve for x:
x=−51.
Therefore, the solution to the equation is x=−51.
