y^{\frac{7}{3}} = 2187

Take both sides of the equation to the power of

\frac{3}{7} : y = 27

y = 27

Verify Solutions:

y = 27

True

The solution is

y = 27

x^{2} + x + 3 = x - 3

3 7 x^{2} - 6 x - 137 = 0

98 - 2 x^{2} + 3 x + 5 + 2 x^{2} - 7 x - 15 = 0

\frac{6 x ^{2}}{( 2 x + 1 + 1 ) ^{2}} = 2 x + x - 1 + 1

c = \frac{1}{( x ^{2} + x - 2 )}
