Question

Solve the system of equations by the addition method. If the system does not have a single ordered pair as a​ solution, state whether the system is inconsistent or dependent. 15x-18=3y 5x=y+6

Answer 1

dependent

Explanation:

The given system is :

15x-18=3y

5x=y+6

Rewrite the equations in standard form to get:

15x-3y=18

5x-y=6

Multiply the bottom equation by 3.

15x-3y=18

15x-3y=18

Sub both equations:

0-0=0

0=0

We got an identity

The system is dependent because there are infinitely many solutions
