 Equation Simplifying Y * 2 + 5Y = 3 + 4(Y + 3) Reorder the terms for easier multiplication: 2Y + 5Y = 3 + 4(Y + 3) Combine like terms: 2Y + 5Y = 7Y 7Y = 3 + 4(Y + 3) Reorder the terms: 7Y = 3 + 4(3 + Y) 7Y = 3 + (3 * 4 + Y * 4) 7Y = 3 + (12 + 4Y) Combine like terms: 3 + 12 = 15 7Y = 15 + 4Y Solving 7Y = 15 + 4Y Move all terms containing Y to the left, all other terms to the right. Add '-4Y' to each side of the equation. 7Y + -4Y = 15 + 4Y + -4Y Combine like terms: 7Y + -4Y = 3Y 3Y = 15 + 4Y + -4Y Combine like terms: 4Y + -4Y = 0 3Y = 15 + 0 3Y = 15 Divide each side by '3'.
