15=9-1/2 x

15 = 9 - \frac{1}{2} x

x = - 12

Solution steps

15 = 9 - \frac{1}{2} x

Switch sides

9 - \frac{1}{2} x = 15

Move

9

to the right side

- \frac{1}{2} x = 6

Multiply both sides by

- 2

x = - 12

\frac{4 a ^{3} + 16 ab - 4 a ^{2}}{2 a ^{2} b}

4 x > - 16 or 6 x \leq - 48

5 x^{2} + 40 x + 80 = 0

2 x - \frac{5}{3} = 7

- \frac{ln ( \frac{4}{5} )}{ln ( \frac{1.05}{1.035} )}
