It is an expression in two variables, x and y.
Thanks to the browser, it is not possible to tell what the inequalities are.

If you mean: y = 2x+5 then it is a straight line equation.
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
That is 27 x 9 = 243

Since there is no equality (or inequality) sign in the question, there is no equation or inequality) and therefore nothing which can be solved.
The y value will equal 15, when x = 7
The answer is 252, Exept, you added a "p" at the end. Is this just a misspelling, or does it mean something?
