x = –9
7x − 10y = 17

Sagot :

Answer:

y = -8

Step-by-step explanation:

This problem is solved using substitution. So you need to start by substituting in the -9 for the 'x' in the main equation. This will give you something that looks like this:

[tex]7(-9)-10y=17[/tex]

Now just solve!

[tex]7(-9)-10y=17\\\\-63-10y=17\\\\-10y=80\\\\y=-8[/tex]

Hope this helps :)
