Simplifying 7y + -1(4 + -2y) = 3(y + 2) 7y + (4 * -1 + -2y * -1) = 3(y + 2) 7y + (-4 + 2y) = 3(y + 2) Reorder the terms: -4 + 7y + 2y = 3(y + 2) Combine like terms: 7y + 2y = 9y -4 + 9y = 3(y + 2) Reorder the terms: -4 + 9y = 3(2 + y) -4 + 9y = (2 * 3 + y * 3) -4 + 9y = (6 + 3y) Solving -4 + 9y = 6 + 3y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-3y' to each side of the equation. -4 + 9y + -3y = 6 + 3y + -3y Combine like terms: 9y + -3y = 6y -4 + 6y = 6 + 3y + -3y Combine like terms: 3y + -3y = 0 -4 + 6y = 6 + 0 -4 + 6y = 6 Add '4' to each side of the equation. -4 + 4 + 6y = 6 + 4 Combine like terms: -4 + 4 = 0 0 + 6y = 6 + 4 6y = 6 + 4 Combine like terms: 6 + 4 = 10 6y = 10 Divide each side by '6'. y = 1.666666667 Simplifying y = 1.666666667
