The y value will equal 15, when x = 7
Thanks to the browser, it is not possible to tell what the inequalities are.

Without any equality signs the given expressions can't be considered to be equations so therefore there are no solutions.

y2x - just double the coordinate of y to get x. xy12 - i have no idea
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
No, alkaline solutions have pH values above 7. pH values below 7 indicate acidic solutions. A pH of 7 is considered neutral.
Basic solutions have a higher concentration of hydroxide ions (OH-) compared to acidic solutions. This property allows basic solutions to have a pH greater than 7, while acidic solutions have a pH less than 7.

One solution.
Equations: 3x-5y = 16 and xy = 7 Solutions: (7, 1) and (-5/3, -21/5)
