a=(d(y+12))/y

a = \frac{d ( y + 12 )}{y}

y = \frac{12 d}{a - d}; a \neq = d

Solution steps

a = \frac{d ( y + 12 )}{y}

Multiply both sides by

y

a y = d (y + 12)

Expand

d (y + 12) : d y + 12 d

a y = d y + 12 d

Move

d y

to the left side

a y - d y = 12 d

Factor

a y - d y : y (a - d)

y (a - d) = 12 d

Divide both sides by

a - d; a \neq = d

y = \frac{12 d}{a - d}; a \neq = d

\frac{13 + 2 x}{4 x + 1} = \frac{3}{4}

\frac{20}{- d} = - 15

x, \frac{3}{x} + 7 y + z = 9

\frac{5}{x + 2} - \frac{2 x - 1}{5} = 0

\frac{8 x}{x + 1} = 4 - \frac{8}{x + 1}
