D. 0
E. no solution

Answer 1

Could someone please walk me through the steps to solve this please?

Answer 2

well.. do you know how to solve linear equations?

Answer 3

x = 2y -2 , since 2y-2 equals x you substitute it in the other equation
3x -y = 14

Answer 4

x = 2y -2 , since 2y-2 equals x you substitute it in the other equation
3(2y-2) -y = 14

Answer 5

now distribute and solve for y
