Question

Which equation shows the result of substituting y from the first quation into the second equation for the given system ? Y = x + 5 y - 2x = 2

Answer 1

see explanation

Explanation:

substituting y = x + 5 into y - 2x = 2, gives

x + 5 - 2x = 2

Answer 2

`x+5-2x=2`

`5-x=2`

Explanation:

`y = x + 5`

`y - 2x = 2`

substituting y from the first equation into the second equation

We are given with first equation
`y = x + 5`

We plug in x+5 for y in second equation

`y - 2x = 2`, Replace y with x+5

`x+5-2x=2`

combine like terms

x-2x is -x

`5-x=2`
