Full solution

Q. 12(5+2y)=4y(59y)12(5+2y)=4y - (5 - 9y)
  1. Distribute 1212: Distribute 1212 to the terms inside the parentheses.\newline12(5)+12(2y)=4y(59y)12(5) + 12(2y) = 4y - (5 - 9y)\newline60+24y=4y5+9y60 + 24y = 4y - 5 + 9y
  2. Combine like terms: Combine like terms on the right side.\newline60+24y=13y560 + 24y = 13y - 5
  3. Subtract 13y13y: Subtract 13y13y from both sides to get all yy terms on one side.\newline60+24y13y=13y13y560 + 24y - 13y = 13y - 13y - 5\newline60+11y=560 + 11y = -5
  4. Subtract 6060: Subtract 6060 from both sides to isolate the yy term.\newline60+11y60=56060 + 11y - 60 = -5 - 60\newline11y=6511y = -65
  5. Divide by 1111: Divide both sides by 1111 to solve for yy.11y11=6511\frac{11y}{11} = \frac{-65}{11}y=5y = -5
