To solve the equation 3x + 1 = 19, you need to isolate the variable x.
Step 1: Subtract 1 from both sides of the equation:
3x + 1 - 1 = 19 - 1
3x = 18
Step 2: Divide both sides of the equation by 3 to solve for x:
3x/3 = 18/3
x = 6
Therefore, the solution to the equation 3x + 1 = 19 within the given set {3, 4, 5, 6} is x = 6.
3x + 1 = 19 {3, 4, 5, 6}
