Question

Find the solution of this system of equations

8x - 4y = -32
-3x + 4y = 42
Enter the correct answer.

Answer 1

x=2, y=12

Explanation:

8x - 4y = -32

-3x + 4y = 42

add the two equations together to eliminate y

8x - 4y = -32

-3x + 4y = 42

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

5x = 10

Divide by 5

5x/5 = 10/5

x=2

Now find y

-3x+4y = 42

-3(2) +4y = 42

-6 +4y = 42

Add 6 to each side

-6+6 +4y = 42+6

4y = 48

Divide by 4

4y/4 =48/4

y=12
