Question

Solve the system of equations -8x+7y=6 and 3x-2y=4 by combining the equations

Answer 1

x=8, y=10. (8, 10).

Explanation:

-8x+7y=6

3x-2y=4

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

2(-8x+7y)=2(6)

7(3x-2y)=7(4)

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

-16x+14y=12

21x-14y=28

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

5x=40

x=40/5

x=8

3(8)-2y=4

24-2y=4

2y=24-4

2y=20

y=20/2

y=10
