Answer: Substituion method
Detailed Explanation:
Substitution method is used by finding the value of one variable in terms of the other, and then substituting that value in one of the equations, hence finding the original value of a variable. Then, we use that value of a variable and substitute it in any one of the equations to find the original value of the second variable.
