Which of the following gives a valid reason for using the given solution method to solve the system of equations shown? Equation 1: 4x = 4 + 8y

Equation 2: 2x + 3y = 2

Substitution: equation 1 can be solved for x in one step by dividing both sides by 4
Elimination; a coefficient in Equation 2 is an integer multiple of a coefficient in Equation 1

Substitution: equation 2 can be solved for x in one step by subtracting both sides by 3y

Elimination; a coefficient in Equation I is an integer multiple of a coefficient in Equation 2
