Y=2x-1

5x-4y=1



Is (1,1) (1,1) left parenthesis, 1, comma, 1, right parenthesis a solution of the system?

(1,1) is a solution of the system.

Step-by-step explanation:

Let's solve the system.

y = 2x - 1

5x - 4y = 1

In the first equation, y is already separated as a function of x. So we replace in the second equation;

5x - 4 (2x - 1) = 1

5x - 8x + 4 = 1

4 - 1 = 8x - 5x

x = 1

y = 2x - 1 = 2 (1) - 1 = 1

(1,1) is a solution of the system.
