1. Problem Description

We are given a system of two linear equations:
5x+y=145x + y = 14
3xy=103x - y = 10
We need to find the solution to this system of equations by graphing. Based on the graphing, we need to choose whether the system has a unique solution, infinitely many solutions, or no solution. If there is a unique solution, we need to provide the ordered pair (x,y)(x, y).

2. Solution Steps

First, let's rewrite each equation in slope-intercept form (y=mx+by = mx + b).
Equation 1: 5x+y=145x + y = 14
Subtract 5x5x from both sides:
y=5x+14y = -5x + 14
Equation 2: 3xy=103x - y = 10
Subtract 3x3x from both sides:
y=3x+10-y = -3x + 10
Multiply both sides by -1:
y=3x10y = 3x - 10
Now we have the equations in slope-intercept form:
y=5x+14y = -5x + 14
y=3x10y = 3x - 10
To find the solution, we set the two equations equal to each other:
5x+14=3x10-5x + 14 = 3x - 10
Add 5x5x to both sides:
14=8x1014 = 8x - 10
Add 10 to both sides:
24=8x24 = 8x
Divide by 8:
x=3x = 3
Now, substitute x=3x = 3 into either equation to find yy. Let's use y=3x10y = 3x - 10:
y=3(3)10y = 3(3) - 10
y=910y = 9 - 10
y=1y = -1
Therefore, the solution is (3,1)(3, -1).

3. Final Answer

A. The solution to this system is (3, -1).
