Use the substitution method to solve the system of equations. Choose the correct ordered pair. 14x - 2y = 78 2x - 2y = 6

(6, 3)

Step-by-step explanation:

Step 1: Rearrange 2nd equation

2x = 2y + 6

x = y + 3

Step 2: Substitution

14(y + 3) - 2y = 78

14y + 42 - 2y = 78

12y + 42 = 78

12y = 36

y = 3

Step 3: Plug in y to find x

2x - 2(3) = 6

2x - 6 = 6

2x = 12

x = 6

Solution,

Putting the value of x from equation (i)

Now, putting the value of y in equation (i)

Value of X is 6

Value of y is 3
