No
Step-by-step explanation:
To check if (2,3) is a solution to the system of equations, we simply have to plug the coordinate points into the two equations and see if it is valid.
![2*2+5*3=\\4+15=\\19\\\\19=19](/tpl/images/1368/8882/68bd6.png)
(2,3) belongs in the first equation.
![2+16*3=\\2+48=\\50\\\\50\neq 5](/tpl/images/1368/8882/6d9a9.png)
(2,3) does not belong in the second equation.
Therefore, (2,3) is not a solution to this system of equations.
