(3(7n+13))/(12n+15)=2

\frac{3 ( 7 n + 13 )}{12 n + 15} = 2

n = 3

Solution steps

\frac{3 ( 7 n + 13 )}{12 n + 15} = 2

Simplify

\frac{3 ( 7 n + 13 )}{12 n + 15} : \frac{7 n + 13}{4 n + 5}

\frac{7 n + 13}{4 n + 5} = 2

Multiply both sides by

4 n + 5

7 n + 13 = 2 (4 n + 5)

Expand

2 (4 n + 5) : 8 n + 10

7 n + 13 = 8 n + 10

Move

13

to the right side

7 n = 8 n - 3

Move

8 n

to the left side

- n = - 3

Divide both sides by

- 1

n = 3

Verify Solutions

Find undefined (singularity) points:

n = - \frac{5}{4}

Combine undefined points with solutions:

n = 3

π = \frac{2 π}{x}

t, v = \frac{s}{t}

x = 2.1 + 3 (\frac{12}{( 3 x )})

\frac{100 P - 4000}{100 P} = 0.3

\frac{5}{x} + 4 = 12
