Q. Solve for cc.\newline9c−18c−11c=−209c - 18c - 11c = -20\newlinec=c = __
  1. Combine like terms: Combine like terms on the left side of the equation.\newline9c−18c−11c=−209c - 18c - 11c = -20\newline(9−18−11)c=−20(9 - 18 - 11)c = -20\newline(−20)c=−20(-20)c = -20
  2. Divide both sides: Divide both sides by −20-20 to solve for cc.−20c−20=−20−20\frac{-20c}{-20} = \frac{-20}{-20}c=1c = 1
