Answer:

x = x; the solution has infinite solutions

Step-by-step explanation:

3(x+ 7) = 3x + 21; distribute the 3 on the left side

3x + 21 = 3x + 21; now subtract 21 from both sides

3x = 3x; divide by 3

x = x; the solution has infinite solutions. Since both terms are equal any value for x will be true on this equation.
