Question

enter the value for x that makes the equation $2(x - 3)+21=-3$ true.
$x = \square$

Explanation:

Step1: Simplify the left side

First, distribute the 2 in \(2(x - 3)\): \(2x - 6\). Then add 21: \(2x - 6 + 21 = 2x + 15\). So the equation becomes \(2x + 15 = -3\).

Step2: Isolate the variable term

Subtract 15 from both sides: \(2x + 15 - 15 = -3 - 15\), which simplifies to \(2x = -18\).

Step3: Solve for x

Divide both sides by 2: \(\frac{2x}{2} = \frac{-18}{2}\), so \(x = -9\).

Answer:

\(-9\)
