Step-by-step explanation:
<u>Step 1: Define</u>
-7 - 3x = 1x + 4(2 + x)
<u>Step 2: Solve for </u><em><u>x</u></em>
Distribute 4: -7 - 3x = x + 8 + 4x Combine like terms: -7 - 3x = 5x + 8 [Addition Property of Equality] Add 3x on both sides: -7 = 8x + 8 [Subtraction Property of Equality] Subtract 8 on both sides: -15 = 8x [Division Property of Equality] Divide 8 on both sides: -15/8 = x Rewrite/Rearrange: x = -15/8
