To verify the given equation, we'll simplify both sides and check if they are equal.
Starting with the left side of the equation:
3(x + 7)
= 3 * x + 3 * 7 (distributing the 3 to both x and 7)
= 3x + 21
Thus, the left side of the equation simplifies to 3x + 21.
Now let's simplify the right side of the equation:
3x + 21
As both sides simplify to 3x + 21, we can conclude that 3(x + 7) is indeed equal to (3x + 21).
3(x + 7) = (3x + 21)
