Answer

x = 0 Using set notation: {x|x = 0}

Work Step by Step

We need to solve the equation: 5 - x = 4x + 5 First, let's add x to both sides of the equation. 5 - x + x = 4x + x + 5 5 = 5x + 5 Next, subtract 5 from both sides of the equation. 5 - 5 = 5x + 5 - 5 0 = 5x Next, divide both sides by 5. $\frac{0}{5}$ = $\frac{5x}{5}$ So that x = 0.
