(5A-3)/(2A+1)= 2/7

\frac{5 A - 3}{2 A + 1} = \frac{2}{7}

A = \frac{23}{31}

Decimal Notation

A = 0.74193 \dots

Solution steps

\frac{5 A - 3}{2 A + 1} = \frac{2}{7}

Cross multiply

35 A - 21 = 4 A + 2

Move

21

to the right side

35 A = 4 A + 23

Move

4 A

to the left side

31 A = 23

Divide both sides by

31

A = \frac{23}{31}

Verify Solutions

Find undefined (singularity) points:

A = - \frac{1}{2}

Combine undefined points with solutions:

A = \frac{23}{31}

\frac{( 3 )}{( x )} = 6

(\frac{28}{y})^{2} + y^{2} = 65

\frac{3}{x} = \frac{7}{4 x} - 2

\frac{7}{4} = \frac{6}{y} - 2

\frac{1}{( x - 2 )} = 3
