Question

Solve the system by elimination. If the system is inconsistent or has dependent equations, say so.7x+ 5y = 5- 35x- 25y = -25

Answer 1

STEP - BY - STEP EXPLANATION

What to find?

Solution to the system.

Given:

7x+ 5y = 5

- 35x- 25y = -25

By elimination method;

Step 1

Multiply through the first equation by -5.

-35x - 25y = -25

Step 2

Add the first and third equation.

0= 0

Step 3

Draw a conclusion from the result.

Since, 0= 0, it implies that the system has an infinite many solution hence it is a dependent system.

ANSWER

It is a dependent system.
