Question

For the following system, use the second equation to make a substitution for x in the first equation.

x + 5y - 10 = 0
x = 2y - 8

What is the resulting equation in simplest form?

Answer 1

Replace x with 0 and simplify.x,x+5y- 10=0, x = 2 y − 8

Explanation:

Answer 2

The resulting equation is
`2y-8 + 5y - 10 = 0`

Explanation:

For the following system, use the second equation to make a substitution for x in the first equation.

`x + 5y - 10 = 0` first equation

`x = 2y - 8` second equation

Now substitute the second equation in first equation

Replace x with 2y-8 in first equation

`x + 5y - 10 = 0`

`2y-8 + 5y - 10 = 0`

The resulting equation is
`2y-8 + 5y - 10 = 0`
