1. Problem Description

The problem is to solve the system of inequalities:
5x+y>65x + y > 6
x2y>7x - 2y > 7

2. Solution Steps

We need to solve the system of inequalities.
First, let's isolate yy in both inequalities.
For the first inequality, 5x+y>65x + y > 6, we subtract 5x5x from both sides:
y>5x+6y > -5x + 6
For the second inequality, x2y>7x - 2y > 7, we subtract xx from both sides:
2y>x+7-2y > -x + 7
Now, divide by 2-2. Remember to flip the inequality sign when dividing by a negative number:
y<12x72y < \frac{1}{2}x - \frac{7}{2}
Now we have the two inequalities in slope-intercept form:
y>5x+6y > -5x + 6
y<12x72y < \frac{1}{2}x - \frac{7}{2}
We cannot give a numerical solution for xx and yy, but rather describe the region where both inequalities hold true. The solution set consists of all points (x,y)(x, y) that satisfy both inequalities.

3. Final Answer

The solution to the system of inequalities is given by:
y>5x+6y > -5x + 6
y<12x72y < \frac{1}{2}x - \frac{7}{2}
The solution is the region where both these inequalities are satisfied.
