Find the range of values of x for which 3x - 7 \(\leq\) 0 and x + 5 > 0?

 Factorize completely \(\frac{x^{3} + 3x^{2} - 10x}{2x^{2} - 8}\)

If p and q are two non zero numbers and 18(p+q) = (18+p)q, which of the following must be true?

Solve the simultaneous equations \(\frac{2}{x} - {\frac{3}{y}}\) = 2, \(\frac{4}{x} + {\frac{3}{y}}\) = 10

Solve the simultaneous equations 2x - 3y = -10,  10x - 6y = -5
