1/(x+3)+4=(21)/(x+3)

\frac{1}{x + 3} + 4 = \frac{21}{x + 3}

x = 2

Solution steps

\frac{1}{x + 3} + 4 = \frac{21}{x + 3}

Multiply both sides by

x + 3

1 + 4 (x + 3) = 21

Move

1

to the right side

4 (x + 3) = 20

Divide both sides by

4

x + 3 = 5

Move

3

to the right side

x = 2

Find undefined (singularity) points:

x = - 3

Combine undefined points with solutions:

x = 2

135 = \frac{180 ( n - 2 )}{n}

m, a = \frac{f}{m}

3 x^{2} - 6 x - 4 = - \frac{2}{x + 3} + 1

\frac{5 x}{3 x - 6} = \frac{3}{2}

\frac{10}{x} = x - 3
