The correct Answer is:
To solve the equation \(3x + 2(x + 2) = 20 - (2x - 5)\), follow these steps: ### Step 1: Distribute the terms Distribute \(2\) in \(2(x + 2)\) and \(-1\) in \(-(2x - 5)\). \[ 2(x + 2) = 2x + 4 \] \[ -(2x - 5) = -2x + 5 \] Now, rewrite the equation: \[ 3x + 2x + 4 = 20 - 2x + 5 \] ### Step 2: Simplify both sides Combine like terms on both sides of the equation. On the left side: \[ 3x + 2x + 4 = 5x + 4 \] On the right side: \[ 20 + 5 - 2x = 25 - 2x \] So, the equation now looks like: \[ 5x + 4 = 25 - 2x \] ### Step 3: Move all terms involving \(x\) to one side Add \(2x\) to both sides to move the \(x\) terms to the left side: \[ 5x + 2x + 4 = 25 \] This simplifies to: \[ 7x + 4 = 25 \] ### Step 4: Move constant terms to the other side Subtract \(4\) from both sides: \[ 7x = 25 - 4 \] This simplifies to: \[ 7x = 21 \] ### Step 5: Solve for \(x\) Divide both sides by \(7\): \[ x = \frac{21}{7} \] This simplifies to: \[ x = 3 \] ### Final Answer The solution to the equation is: \[ \boxed{3} \] ---
