Question

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

Answer 1

x= -4.5

Explanation:

-2x - 5 = 4

-2x = 4+5

-2x = 9

-2x÷ (-2) = 9÷ (-2)

x= -9/2

x= -4.5

Answer 2

x = -4.5

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
