$6$

Work Step by Step

Using order of operations, the given expression, $ \dfrac{4\cdot6+5\cdot3}{7+2\cdot3}+\dfrac{7\cdot9+6\cdot5}{3\cdot5+8\cdot2} ,$ simplifies to \begin{array}{l}\require{cancel} \dfrac{24+15}{7+6}+\dfrac{63+30}{15+16} \\\\= \dfrac{39}{13}+\dfrac{93}{31} \\\\= 3+3 \\\\= 6 .\end{array}
