1. Problem Description

The problem is to solve the system of linear equations:
4x+y=64x + y = 6
3xy=83x - y = 8

2. Solution Steps

We can solve this system of equations using elimination.
Add the two equations together:
(4x+y)+(3xy)=6+8(4x + y) + (3x - y) = 6 + 8
7x=147x = 14
Divide both sides by 7:
x=147x = \frac{14}{7}
x=2x = 2
Now, substitute the value of xx into either of the original equations to solve for yy.
Let's use the first equation:
4x+y=64x + y = 6
4(2)+y=64(2) + y = 6
8+y=68 + y = 6
Subtract 8 from both sides:
y=68y = 6 - 8
y=2y = -2

3. Final Answer

The solution to the system of equations is x=2x = 2 and y=2y = -2.
So the solution is (2,2)(2, -2).
