Answer:
(-4,17)
Step-by-step explanation:
2x-3y=-11
2x+y=9
solve the equation
x=-4
2x+y=9
substitute the value of x into an equation
2×(-4)+y=9
solve the equation
y=17
A possible solution is
(-4,17)
check the solution
2×(-4)-3=-11
2×(-4)+17=9
simplify
-11=-11
9=9
the order pair is a solution
answer is (-4,17)
