Vikentia [17]

Answer:

(1/7, 1)

Step-by-step explanation:

By "answer," you probably meant "solution." What is the "solution of the system of linear equations

- 5y = - 5

+ 7x +6y=7

The first eqation can be solved for y: y = 1. Substitute 1 for y in the secon equation. Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.

The solution to this system is (1/7, 1)
