Math Problem Statement

-2(2x+y)=28

Solution

Let's solve the equation 2(2x+y)=28-2(2x + y) = 28.

Step 1: Distribute the 2-2 to both terms inside the parentheses:

2(2x+y)=22x2y=4x2y-2(2x + y) = -2 \cdot 2x - 2 \cdot y = -4x - 2y So, the equation becomes: 4x2y=28-4x - 2y = 28

Step 2: Divide the entire equation by 2-2 to simplify:

4x2y2=282\frac{-4x - 2y}{-2} = \frac{28}{-2} This simplifies to: 2x+y=142x + y = -14

Final Answer:

The simplified equation is: 2x+y=142x + y = -14
