Question

Solve the system of equations below. express your answer as an ordered pair in the format (a,b), with no spaces between the numbers are symbols.
2x+5y=16
-5x-2y=2

Answer 1

5(2x+5y=16)+2(-5x-2y=2)

10x-10x+25y-4y=80+4

21y=84

y=4, making 2x+5y=16 become:

2x+5(4)=16

2x+20=16

2x=-4

x=-2

So the solution to the system of equations is the point (-2, 4)
