## Intermediate Algebra for College Students (7th Edition)

The solution set is $\left\{13\right\}$.
Subtract $x$ and add $7$ to both sides; then combine like terms to find: $2x-7-x+7=6+x-x+7 \\x=13$ Check: $2(13)-7\stackrel{?}{=}6+13 \\26-7\stackrel{?}{=}19 \\19 \stackrel{\checkmark}{=}19$ The solution set is $\left\{13\right\}$.
