Question

Solve.

x = –9
7x − 10y = 17

Answer 1

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:

$7(-9)-10y=17$

Now just solve!

$7(-9)-10y=17\\\\-63-10y=17\\\\-10y=80\\\\y=-8$

Hope this helps :)
