Sounds like a system of equations.
Y + 5X = - 2
- 15X - 3Y = 6
substitution using first equation
Y + 5X = - 2
Y = - 5X - 2
==========insert into other equation as this is Y
- 15X - 3(- 5X - 2) = 6
- 15X + 15X + 6 = 6
========================This looks to be a dependent system that has an infinite number of solutions
