Answer 2

Solving the Equation

To solve the equation 4*(-5-3y)-y=7, we can follow these steps:

1. Distribute the 4 to the terms inside the parentheses: 4*(-5-3y) = -20 - 12y. 2. Substitute the expression -20 - 12y back into the equation: -20 - 12y - y = 7. 3. Combine like terms: -13y - 20 = 7. 4. Add 20 to both sides of the equation: -13y = 27. 5. Divide both sides of the equation by -13 to solve for y: y = -27/13.

Therefore, the solution to the equation 4*(-5-3y)-y=7 is y = -27/13.
