Final answer:
To simplify the equation 815 = 3x, divide both sides of the equation by 3 to isolate the variable x. The solution to the equation is x = 271.
Step-by-step explanation:
To simplify the equation 815 = 3x, we need to isolate the variable x on one side of the equation.
To do this, we divide both sides of the equation by 3 to cancel out the coefficient of x.
This gives us x = 815/3. Performing the division, we get x = 271.
Therefore, the solution to the equation is x = 271.
