How to Solve for x in the Simplest Way
Let’s go through a simple example to solve for \( x \) in the equation:
2x + 3 = 7
- Step 1: Isolate the term with \( x \)
To isolate the term with \( x \), we need to move the constant term (3) to the other side of the equation. We do this by subtracting 3 from both sides:2x + 3 - 3 = 7 - 3 2x = 4
- Step 2: Solve for \( x \)
Now that we have isolated the term with \( x \), we need to solve for \( x \). Since \( x \) is multiplied by 2, we divide both sides of the equation by 2:2x / 2 = 4 / 2 x = 2
So, the solution to the equation 2x + 3 = 7 is x = 2.
This is the simplest way to solve for \( x \) in a linear equation. By isolating the term with \( x \) and then solving for it, you can find the value of \( x \) easily!
