The solution set is $\left\{9\right\}$.

Work Step by Step

Solve using the different properties of Algebra to find: $5x-2x-(-8)=35 \\3x+8=35 \\3x=35-8 \\3x=27 \\x=\frac{27}{3} \\x=9$ Check: $5(9)-(2\cdot9 -8)\stackrel{?}{=}35 \\45-(18-8)\stackrel{?}{=}35 \\45-10\stackrel{?}{=}35 \\35 \stackrel{\checkmark}{=}35$ The solution set is $\left\{9\right\}$.
