-1/2 x-(-3)-x=15

- \frac{1}{2} x - (- 3) - x = 15

x = - 8

Solution steps

- \frac{1}{2} x - (- 3) - x = 15

Apply rule

- (- a) = a

- \frac{1}{2} x + 3 - x = 15

Group like terms

- \frac{1}{2} x - x + 3 = 15

Move

3

to the right side

- \frac{1}{2} x - x = 12

Multiply both sides by

2

- 3 x = 24

Divide both sides by

- 3

x = - 8

6 b^{2} - 5 b = 4

\frac{x}{7} = - 3

1 - e^{- \frac{80}{25}}

24 = 3 - (- x - 16)

4 p^{2} - p = 0
