(45)/(x+3)=(20)/(10-x)

\frac{45}{x + 3} = \frac{20}{10 - x}

x = 6

Solution steps

\frac{45}{x + 3} = \frac{20}{10 - x}

Cross multiply

450 - 45 x = 20 x + 60

Move

450

to the right side

- 45 x = 20 x - 390

Move

20 x

to the left side

- 65 x = - 390

Divide both sides by

- 65

x = 6

Verify Solutions

Find undefined (singularity) points:

x = - 3, x = 10

Combine undefined points with solutions:

x = 6

100 = \frac{1600}{( 1 + r ) ^{2}}

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

2 = \frac{4}{3} - \frac{5}{z}

2 = \frac{4}{3} - \frac{5}{y}

x, 0 = \frac{y - x}{y + x}
