Is (2, 3) a solution to this system of equations?<br> 2x + 5y = 19<br> X + 16y = 5<br> yes<br> no
chubhunter [2.5K]

Answer:

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

(2,3) belongs in the first equation.

2+16*3=\\2+48=\\50\\\\50\neq 5

(2,3) does not belong in the second equation.

<u>Therefore, (2,3) is not a solution to this system of equations.</u>
