Explanation:

Step 1: Define

-7 - 3x = 1x + 4(2 + x)

Step 2: Solve for x

1. Distribute 4: -7 - 3x = x + 8 + 4x
2. Combine like terms: -7 - 3x = 5x + 8
3. [Addition Property of Equality] Add 3x on both sides: -7 = 8x + 8
4. [Subtraction Property of Equality] Subtract 8 on both sides: -15 = 8x
5. [Division Property of Equality] Divide 8 on both sides: -15/8 = x
6. Rewrite/Rearrange: x = -15/8
