Solve for X in the Equation: 3-x+7=5 | Linear Equation Solution

To solve this problem, we'll follow these steps:

• Step 1: Simplify the given equation by combining like terms.
• Step 2: Isolate the variable $x$ on one side of the equation.
• Step 3: Solve the resulting simplified equation for $x$.

Now, let's work through each step:

Step 1: Simplify the given equation:

The original equation is: $3 - x + 7 = 5$.

Combine like terms on the left side of the equation:

$3 + 7 = 10$, so the equation becomes:

$10 - x = 5$.

Step 2: Isolate the variable $x$:

Subtract 10 from both sides of the equation to move the constant term:

$-x = 5 - 10$.

Simplify the right side:

$-x = -5$.

Step 3: Solve for $x$:

Multiply both sides of the equation by $-1$ to solve for $x$:

$x = 5$.

Therefore, the solution to the problem is $x = 5$.
