Question

In the equation 15 - x = 2(x + 3) what is your first step? *

Answer 1

Answer: Distributive Property, follow PEMDAS (the first is parenthesis)

x = 3

Explanation:

1. Distribute 2 into (x-3). 15 - x = 2x + 6.
2. Add x on both sides. 15 = 3x + 6.
3. Subtract 6 on both sides. 9 = 3x.
4. Divide 3 on both sides. x = 3

Answer 2

Your first step is to distribute the 2 in 2(x+3)

Explanation:

The after you complete this step you will make the equation look like

- x - 2x = 6 - 15.

Work it out like you would normally do!
