What will be the value of x if the expression 7x + 3 = 24 is solved?

Explanation:
To find the value of x in the equation 7x + 3 = 24, you need to isolate the variable x. First, you can start by subtracting 3 from both sides of the equation: 7x + 3 - 3 = 24 - 3 This simplifies to: 7x = 21 Next, to solve for x, divide both sides by 7: 7x / 7 = 21 / 7 This simplifies to: x = 3 Thus, the correct answer is 3, which corresponds to the value of x that solves the original equation. This process of isolating the variable involves basic algebraic manipulations, and understanding these steps is key in solving linear equations.

To find the value of x in the equation 7x + 3 = 24, you need to isolate the variable x. First, you can start by subtracting 3 from both sides of the equation:

7x + 3 - 3 = 24 - 3

This simplifies to:

7x = 21

Next, to solve for x, divide both sides by 7:

7x / 7 = 21 / 7

This simplifies to:

x = 3

Thus, the correct answer is 3, which corresponds to the value of x that solves the original equation. This process of isolating the variable involves basic algebraic manipulations, and understanding these steps is key in solving linear equations.
