Question

Find the solution of the system of equations.
15x – 4y = -50
3x – 2y = –16

Answer 1

x=-2, y=5. (-2, 5).

Explanation:

15x-4y=-50

3x-2y=-16

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

15x-4y=-50

-5(3x-2y)=-5(-16)

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

15x-4y=-50

-15x+10y=80

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

6y=30

y=30/6

y=5

3x-2(5)=-16

3x-10=-16

3x=-16+10

3x=-6

x=-6/3

x=-2
