Question

Create an equivalent system of equations using the sum of the system and the first equation.

Answer 1

Answer:

x+4y=8

5x+5y=10

Step-by-step explanation:

Answer 2

Answer:

$x+4y=8\\5x+5y=10$

Step-by-step explanation:

Given:

$x + 4y = 8\\4x + y = 2$

Adding the above two equations, we get

$x + 4y+4x + y= 8+2\\x+4x+4y+y=10\\5x+5y=10$

Therefore, an equivalent system of equations using the sum of the system and the first equation is :

$x+4y=8\\5x+5y=10$
