Step-by-step explanation:
<u>Step 1: Define Equation</u>
x + 5 = -3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 5 on both sides: x = -8
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: -8 + 5 = -3
- Add: -3 = -3
Here we see that -3 does indeed equal -3.
∴ x = -8 is the solution to the equation.
