Answer

\( x=-8 \)

Solution

Solve the equation \( 2x+3=x-5 \). Solve the equation by following steps: - step0: Solve for \(x\): \(2x+3=x-5\) - step1: Move the expression to the left side: \(2x-x=-5-3\) - step2: Add and subtract: \(x=-5-3\) - step3: Add and subtract: \(x=-8\) The solution to the equation \(2x+3=x-5\) is \(x=-8\).

The Deep Dive

To solve the equation \( 2x + 3 = x - 5 \), start by isolating \( x \) on one side. First, subtract \( x \) from both sides to get \( 2x - x + 3 = -5 \), simplifying to \( x + 3 = -5 \). Next, subtract 3 from both sides, resulting in \( x = -5 - 3 \), which gives you \( x = -8 \). Now, you can plug \( x = -8 \) back into the original equation to check your solution: \( 2(-8) + 3 = -8 - 5 \) simplifies to \( -16 + 3 = -8 - 5 \), which ultimately results in \( -13 = -13 \). The solution checks out!
