Answer 1

Let's solve the equation step by step.

Given the equation: $$2(x-3)+21=-3$$

Step 1: Distribute to get Response area We will distribute the $2$ in the left-hand side: $$2\cdot x-2\cdot 3+21=-3$$ This simplifies to: $$2x-6+21=-3$$

Response area: $2x-6+21=-3$

Step 2: Combine like terms to get Response area Now, we combine the like terms $-6$ and $21$: $$2x+15=-3$$

Response area: $2x+15=-3$

---

Step 3: Use the (choose a property) Response area to get (resulting equation) Response area Next, we will use the Subtraction Property to isolate $2x$ by subtracting $15$ from both sides: $$2x+15-15=-3-15$$ This simplifies to: $$2x=-18$$

Response area: $2x=-18$

---

Step 4: Use the (choose a property) Response area to get (resulting answer) Response area Now, we will use the Division Property to solve for $x$ by dividing both sides by $2$: $$x=\frac{-18}{2}$$ This simplifies to: $$x=-9$$

Response area: $x=-9$

---

So, the final answer is $x=-9$.
