Full solution

Q. What value of w w makes the equation below true?\newline5w+1=21 5 w+1=21 \newline33\newline44\newline1414\newline2121
  1. Isolate variable w: First, we need to isolate the variable ww on one side of the equation. To do this, we should subtract 11 from both sides of the equation to get rid of the +1+1 on the left side.\newlineCalculation: 5w+11=2115w + 1 - 1 = 21 - 1
  2. Simplify both sides: Now, we simplify both sides of the equation after subtracting 11.\newlineCalculation: 5w=205w = 20
  3. Divide by 55: Next, we divide both sides of the equation by 55 to solve for ww.\newlineCalculation: 5w5=205\frac{5w}{5} = \frac{20}{5}
  4. Calculate ww: Finally, we calculate the value of ww.\newlineCalculation: w=4w = 4
