Answer:

A (-1,-6)

Step-by-step explanation:

A system of equations is a set of two or more equations which intersect at a point (x,y). This is the solution. Any system can be solved using graphing, elimination or substitution. To solve this system of equations, use elimination. Line up each variable and subtract the like terms.

2x - 3y = 16

5x - 3y = 13

---------------------

-3x      = 3

x = -1

Substitute x = -1

2(-1) - 3y = 16

-2 - 3y = 16

-3y = 18

y = -6
