Question

Solve.
5x– 2y = 27
-3x +2y=-17
Enter your answer, in the form (x,y), in the boxes.

Answer 1

x=5,y=-1

Explanation:

5x– 2y = 27

-3x +2y=-17

Add the two equations together to eliminate y

5x– 2y = 27

-3x +2y=-17

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

2x = 10

Divide by 2

2x/2 = 10/2

x = 5

Now find y

-3x +2y = -17

-3(5)+2y = -17

-15+2y =-17

Add 15 to each side

-15+15 +2y = -17+15

2y = -2

Divide by 2

2y/2 = -2/2

y =-1
