2x-3y=-11

2x+y=9

What is the answer for this substitution method

(-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)
