Answer 2

Solving the Equation 2(2-y)-y=3

To solve the equation 2(2-y)-y=3, we can follow these steps:

1. Expand and simplify the equation. 2. Solve for the variable y.

Step 1: Expand and Simplify the Equation

First, let's expand and simplify the given equation:

2(2-y)-y=3

Expanding the equation: 4 - 2y - y = 3

Simplifying: 4 - 3y = 3

Step 2: Solve for the Variable y

Now, let's solve for the variable y:

4 - 3y = 3

Subtract 4 from both sides: -3y = -1

Divide by -3: y = 1/3

So, the solution to the equation 2(2-y)-y=3 is y = 1/3.

This solution can be verified by substituting y = 1/3 back into the original equation to ensure it satisfies the equation.
