Answer:

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

Step-by-step 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 $2y-8 + 5y - 10 = 0$

What is 9x-5-8+x= what

Hi there!

First you simplify.

Simplified = 9x+(−5)+(−8)+x

Then you combine the like terms.

9x+(−5)+(−8)+x (*-5 and -8 are like terms) (9x and x are like terms)

Combined it's~ (9x+x)+(−5+−8)

Solve and that comes to 10x+−13 which is your answer. :)

Hope this helps.
