Full solution

Q. Solve.\newline4(2x−9)=−20 4(2 x-9)=-20 \newlineAnswer: x= x=
  1. Distribute 44: Distribute the 44 into the parentheses.4(2x−9)=−204(2x - 9) = -20=4×2x+4×(−9)= 4 \times 2x + 4 \times (-9)=8x−36= 8x - 36
  2. Add 3636: Add 3636 to both sides to isolate the term with xx.\newline8x−36+36=−20+368x - 36 + 36 = -20 + 36\newline8x=168x = 16
  3. Divide by 88: Divide both sides by 88 to solve for x.\newline8x8=168\frac{8x}{8} = \frac{16}{8}\newlinex=2x = 2
