Explanation & Answer
Thank you for the opportunity to help you with your question!
First, let us number the equations,
2x+3y=-3 (i)
x+3/4y=-1/2 (ii)
Let us multiply (ii) by 2 to get
2x+6/4y=-1 (iii)
Now multiply (iii) by -1 to get
-2x-6/4y=1 (iv)
Now let us add (i) and (iv) as shown below
2x+3y-2x-6/4y=-3+1
simplify to get
3y-6/4y=-2
Simplifying you get
3/2y=-2
y=-2 (2/3)=-4/3
Now use (ii) to find x as below
x+3/4y=-1/2
x+(3/4)(-4/3)=-1/2
x-1=-1/2
x=1/2
Let me if you need any further clarification.
Thanks
Please let me know if you need any clarification. I'm always happy to answer your questions.
