The solution to the given inequality is y < 5
<h3>Solving inequality expressions</h3>
Inequality are equations not separated by an equal sign. Given the following parameters
15 > y + 10
Subtract 10 from both sides
15 - 10 > y + 10 - 10
5 > y
Swap
y < 5
Hence the solution to the given inequality is y < 5

2y + 2x = 6
2y - x = 12
Subtract
3x = -6, x = -2
2(-2) + 2y = 6
-4 + 2y = 6
2y = 10, y = 5
Final solution: x = -2, y = 5
