I'm assuming you want to solve for X and Y.
So, you know that Y=-3X+5.
Taking this information, you can substitute -3X+5 for Y in your second equation.
5X-4(-3X+5)=-3
Simplify the left side of the equation by distributing the -4.
5X+12X-20=-3
Combine like terms on the left side.
17X-20=-3
Add 20 to both sides.
17X=17
Divide both sides by 17.
X=1
Now, you substitute 1 for X into the first equation to find Y.
Y=-3(1)+5= -3+5= 2
Final Answer: X=1, Y=2 or (1,2)
