$6x-106$

Without an equal sign, the given is an $\text{ expression }.$ Using $a(b+c)=ab+ac$ or the Distributive Property and then combining like terms, the given expression, $ -7(x+4)+13(x-6) ,$ simplifies to \begin{array}{l}\require{cancel} -7x-28+13x-78 \\\\= (-7x+13x)+(-28-78) \\\\= 6x-106 .\end{array}
