(12x)/(10+x)=7.4

\frac{12 x}{10 + x} = 7.4

x = \frac{370}{23}

Decimal Notation

x = 16.08695 \dots

Solution steps

\frac{12 x}{10 + x} = 7.4

Multiply both sides by

10 + x

12 x = 7.4 (10 + x)

Multiply both sides by

10

120 x = 74 (10 + x)

Expand

74 (10 + x) : 740 + 74 x

120 x = 740 + 74 x

Move

74 x

to the left side

46 x = 740

Divide both sides by

46

x = \frac{370}{23}

Verify Solutions

Find undefined (singularity) points:

x = - 10

Combine undefined points with solutions:

x = \frac{370}{23}

f (x), (f (x))^{- 1} = 17

\frac{3}{x ^{2} - 9} = 0

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

\frac{1 + x}{x} = 5

\frac{24}{2 x} = 1 + x
