What is the solution of the equation 2 (x + 9) = 16?

Question

What is x?

Answer 1

To solve the equation, let's simplify the left side:

2(x + 9) = 16

First, distribute the 2 to both terms inside the parentheses:

2x + 18 = 16

Next, subtract 18 from both sides of the equation:

2x + 18 - 18 = 16 - 18
2x = -2

Finally, divide both sides by 2:

2x/2 = -2/2
x = -1

Therefore, the solution to the equation is x = -1.
