Which of the following gives a valid reason for using the given solution method to solve the system of equations shown?
equation i: 4x − 5y = 4 and equation ii: 2x + 3y = 2
a. elimination; a coefficient in equation i is an integer multiple of a coefficient in equation ii.
b. elimination; a coefficient in equation ii is an integer multiple of a coefficient in equation i.
c. substitution; equation i can be solved for x in one step by dividing both sides by 4.
d. substitution; equation ii can be solved for x in one step by subtracting 3y from both sides.
