$\frac{5(x+2)}{2x-14}$ for $x=10$ substitute 10 for each x $=\frac{5(10+2)}{2\times10-14}$ complete any grouped operations first - remember that the numerator and denominator of a fraction are each considered grouped $=\frac{5\times12}{20-14}$ within each group, first complete multiplication and division in order left to right, then addition and subtraction left to right $=\frac{60}{6}$ finish with division - fractions mean divide the numerator by the denominator $=10$
