Answer:

(-3, 8) is the solution

Step-by-step explanation:

The LCD of the first equation is (3)(4) = 12.  Rewriting this equation, we get:

4x + 3y = 12

to which we add the second equation, obtaining:

4x + 3y = 12

2x - 3y = -30

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

6x   = -18

Dividing both sides by 6 yields x = -3

Substituting -3 for x in the first equation yields 4(-3) + 3y = 12, or

-12 + 3y = 12

Then 3y = 24 and y must be 8.

The solution to this system of linear equations is (-3, 8).
