Answer 1

Answer:

x = 8, y = 3

Step-by-step explanation:

3x - 12y = 60

x + 2y = 14

3x - 12y = 60

3x + 6y = 42 (multiply by 3 so the x is the same as the top equation)

6y = 18 (subtract the equations)

y = 18 / 6

= 3

To find x, substitute y into the 2nd equation since it is the simplest so:

x + 2(3) = 14

x + 6 = 14

x = 14 - 6

= 8
