Solve the equation: 7x = 49.

To solve the equation 7x = 49, the goal is to isolate the variable x. To do this, you need to divide both sides of the equation by 7. This operation will give you the value of x directly.

When you divide 49 by 7, you find that:

49 ÷ 7 = 7.

Thus, when you place the value of x back into the equation, you get:

7(7) = 49, which confirms that the equation holds true.

Therefore, the value of x is indeed 7, making this the correct answer. This understanding is fundamental in solving equations—utilizing inverse operations to isolate the variable is a key skill in algebra.
