What is the solution of the equation 2 (x + 9) = 16 when solving for x

1 answer

To solve the equation 2(x + 9) = 16 for x, we can follow these steps:

1. First, simplify the equation by applying the distributive property.
2(x + 9) becomes 2x + 18.

2. Now the equation becomes 2x + 18 = 16.

3. Next, isolate the variable by subtracting 18 from both sides of the equation.
2x + 18 - 18 = 16 - 18,
2x = -2.

4. Finally, divide both sides of the equation by 2 to solve for x.
2x/2 = -2/2,
x = -1.

So, the solution of the equation 2(x + 9) = 16 is x = -1.
