Question: 1 / 400

What is the solution to the equation 5x − 18 = x/2?

x = 2

x = 4

To solve the equation 5x − 18 = x/2, it's essential to isolate the variable x on one side. Here’s how the solution unfolds:

First, multiply both sides of the equation by 2 to eliminate the fraction. This gives:

2(5x - 18) = x

Expanding the left side results in:

10x - 36 = x

Next, subtract x from both sides to consolidate all x terms on one side:

10x - x - 36 = 0, which simplifies to:

9x - 36 = 0

Now, add 36 to both sides to isolate the term with x:

9x = 36

Finally, divide both sides by 9 to solve for x:

x = 36 / 9 = 4

Thus, the solution to the equation is x = 4.

This confirms that 4 is the correct answer, as all mathematical operations align correctly with solving the equation systematically.

x = 5

x = 3
