Some systems of linear inequalities where the boundary lines are parallel will have a solution. We’ll see this in the next example. Example 6.8.6. Solve the system by graphing: {y > 1 2x − 4 x − 2y < − 4. Solution: {y > 1 2x − 4 x − 2y < − 4. Graph y > 1 2x − 4 by graphing y = 1 2x − 4.

WebSep 29, 2024 · If you had 3 x + 5 < 17, then subtract 5 from both sides and divide by 3 then you will have 3 x < 12, so x < 4 for this case. Since from the quadratic inequality we have 2 < x < 5 (easy to see if you draw a sketch), the solution would be 2 < x < 4. – Alessio K Sep 29, 2024 at 11:16 1 @Gravity098 Yes, it means the same thing. – Andrew Chin
