The solution of the system of equation is (-2 ,2).
<h3>What is a System of Equation ?</h3>
A system of equation is defined as the equation that have a common solution.
The system of equation is
x+y = 0
y = 2x+6
2x-y = -6
3x = -6
x = -2
y = 2
The graph of both the equations are plotted and the common point is the solution of the equations.
The solution of the system of equation is (-2 ,2).

.25x+.10y=$10
.25 because that is the value of the quarter, times x the number or quarters you have and .10 because that is the value of the dime times y, the number of dimes you have.
Answer:
<
Step-by-step explanation:
