+4622 What happens if you multiply the first equation by -3 and the second equation by 2? Let's try it!
If we follow what I said, we will get: 6x+-18y=114 and 6x-8y=64. Now, we can subtract, to attain -10y=50, so y=-5. We can plug the value of y back in the second equation, to get: 3x-4(-5)=32, 3x+20=32, 3x=12, x=4. Thus, the answer is : (4,-5).
