The addition method of solving a system of equations is also known as the elimination method, where one variable is eliminated in order to determine the value of the other.

x + 2y = 0 ----- eq (i)
2x - 6y = 5 ------ eq (ii)
- 2x - 4y = 0 ------ Multiplying eq (i) by - 2 ------ eq (iii)

- 10y = 5 ------ Adding eqs (ii) & (iii)

y = , or

----- Substituting for y in eq (i)

x - 1 = 0

x =
