I can’t see the image — please type the two equations (or paste the image) so I can pick the correct choice.
Meanwhile, here’s how to decide which choice is correct for elimination:
1. Pick a variable to eliminate (x or y).
2. Find multipliers m1 and m2 so that m1*(coefficient of that variable in eqn1) = ± m2*(coefficient of that variable in eqn2).
3. If the two resulting coefficients are opposites (same magnitude, opposite sign) you add the equations; if they are equal (same sign) you subtract one equation from the other.
If you paste the system I’ll apply these steps and tell you which of the four given options is correct.
