Asap ellason wants to solve the following system using the elimination method: 5x + 2y = 30 x + y = 8 what number should the equation x + y = 8 be multiplied by to eliminate y? a)) 2 b)) -2 c)) 5 d)) -5

It should be multiplied by the opposite of the coefficient of y in the first equation, hence
  B)) -2


Actually, it depends on your choice of next step. Multiplying by -2 lets you add the two equations. Multiplying by 2 means you need to subtract one equation from the other. We usually find addition easier, so we would usually choose -2, but either can work. It depends on whether you like to add negative numbers or subtract positive ones.
