(x+3)/(x-3)= 12/3

\frac{x + 3}{x - 3} = \frac{12}{3}

x = 5

Solution steps

\frac{x + 3}{x - 3} = \frac{12}{3}

Cross multiply

3 x + 9 = 12 x - 36

Move

9

to the right side

3 x = 12 x - 45

Move

12 x

to the left side

- 9 x = - 45

Divide both sides by

- 9

x = 5

Verify Solutions

Find undefined (singularity) points:

x = 3

Combine undefined points with solutions:

x = 5

\frac{12 ( 1000 )}{1000 + x} = 2.75

4^{0} = \frac{3 x ^{2} - 2}{4 x + 2}

40 = \frac{130000 - x}{x} 100

0 = - \frac{40}{r ^{2}} + 4 π r

\frac{8}{y} + \frac{17}{y} = 5
