Solve for x:
- 2x - 5 = 4
Hint :add 5 to both sides of the equation?

x = -4.5

Step-by-step explanation:

In order to solve for x, we need to get x alone. We do this by adding 5 to each side, then dividing both sides by -2. Like this:

-2x - 5 = 4

+5          +5

-2x = 9

÷ -2  ÷ -2

x = -4.5

I hope this helps! Please feel free to let me know if you need any more help. Have a great afternoon! :}
