The solution to this problem is the null set or $\left\{\emptyset\right\}$

#### Explanation:

Chandler, because the second equation is already solved for $y$ we can substitute $- 3 x + 4$ for $y$ in the first equation and solve:

$3 x + \left(- 3 x + 4\right) = 10$

$3 x - 3 x + 4 = 10$

$0 + 4 = 10$

Oops,

$4 \ne 10$

Because 4 does not equal 10 the solution to this problem is the null set or $\left\{\emptyset\right\}$
