Answer:
-18
Step-by-step explanation:
Hope that helps
You do 3(-6) to get neg 18
The first equation is 6x - 2y = 10. To solve for y, you will use inverse (opposite) operations to undo what is happening to y. Please see the steps below for the work.
6x - 2y = 10
-6x -6x
<u>-2y </u>= <u>(-6x + 10)</u>
-2 -2
y = 3x - 5
it's 21/21 which would simplify to 1
How I got that answer was by multiplying 3/7 and 7/3 to get 21 both times
