Question

Given the system of linear equations.

-x + y = 17
6x + y = 14
Part A: Use substitution to find the solution to the systems of equations. Include all of your work in your final answer. Part B: Algebraically verify your answer to Part A. Include all of your work in your final answer.

Answer 1

-x + y = 17 --> y = x + 17

6x + (x + 17) = 14 --> x = - 3/7

y = - 3/7 + 17 = 116/7
