(12)/((3x-7)+34)=40

\frac{12}{( 3 x - 7 ) + 34} = 40

x = - \frac{89}{10}

Decimal Notation

x = - 8.9

Solution steps

\frac{12}{( 3 x - 7 ) + 34} = 40

Simplify

\frac{12}{( 3 x - 7 ) + 34} : \frac{4}{x + 9}

\frac{4}{x + 9} = 40

Multiply both sides by

x + 9

4 = 40 (x + 9)

Switch sides

40 (x + 9) = 4

Divide both sides by

40

x + 9 = \frac{1}{10}

Move

9

to the right side

x = - \frac{89}{10}

Verify Solutions

Find undefined (singularity) points:

x = - 9

Combine undefined points with solutions:

x = - \frac{89}{10}

\frac{12}{d} = \frac{9}{3}

\frac{2}{a - 1} = \frac{4}{y}

0 = \frac{4}{x ^{2}}

y = \frac{2}{x - 3}, x

\frac{1}{x} = 11
