Use the substitution method to solve the system of equations. choose the correct ordered pair. 2y + 4x = 18 2y – 3x = 4 a. (6, –3) b. (3, 3) c. (2, 5) d. (5, –1)

 the correct option is (C) (2, 5).

Step-by-step explanation:  We are given to use the substitution method to solve the following system of equations :

Dividing equation equation (i) on both sides by 2, we have

Substituting the value of y from equation (iii) in equation (ii), we get

So, from equation (iii), we get

Thus, the required solution of the given system is (x, y) = (2, 5).

Option (C) is CORRECT.
