-1/2 = 1/2+1/2 x

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

x = - 2

Solution steps

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

Switch sides

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

Move

\frac{1}{2}

to the right side

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

Multiply both sides by

2

x = - 2

1 = 0.8 (1 + (\frac{R ^{1}}{100}))

t, \frac{d N}{d t} = r N

9 x + 1 = 0

4 x - (9 x + 9) + 1 = 5 x - 1

\frac{d + 3}{4} = 5
