G (x) = $frac{3x + 4}{5x - 2}$ + $frac{8x + 1}{- 10x + 4}$
g (x) = $frac{3x + 4}{5x - 2}$ + $frac{8x + 1}{- 2 (5x - 2)}$
y = $frac{2.(34 + 4)}{2(5x - 2)}$ - $frac{8x + 1}{2(5x - 2)}$
y = $frac{6x + 8 - 8x - 1}{2(5x - 2)}$
y = $frac{- 2x + 7}{10x - 4}$
y (10x – 4) = – 2x + 7
10xy – 4y = – 2x + 7
10xy + 2x = 4y + 7
x(10y + 2) = 4y + 7
x = $frac{4y + 7}{10y - 2}$
$g^{-1}$ (x) = $frac{4x + 7}{10x - 2}$
