Question

Find an equivalent system of equations for the following system:

2x + 4y = 4
-5x + 5y = 5

Answer 1

A

Explanation:

x + 2y = 2

-1x + 1y = 5 Is not the correct answer!!!

The options are

a) 2x + 4y = 4

-3x +y = -1

b) 2x + 4y = 4

7x + 5y = -1

c) 2x + 4y = 4

7x - y = 5

d) 2x + 4y = 4

7x - y = -1

Answer 2

x+2y=2

-1x+1y=5

Explanation:

Any system whose equations have the following characteristic

x+2y=2

-1x+1y=1

Is equivalent to the original system, since the differ in a number, the first equation is divided by 2 and the second by 5, we can say any system is equivalent to the original when it is escalated by a factor between its functions.
