Answer:
-9, -8
Step-by-step explanation:
x+(x+1)=7+3(x+1)
x+x+1=7+3(x+1)
2x+1=7+3(x+1)
2x+1=7+3x+3
2x+1=3x+10
2x+1-1=3x+10-1
2x-3x=3x-3x+9
-1x/-1=9/-1
x=-9/-8
When we look at an ordered pair, it will be presented as (x,y)
The first term, x (called the x-coordinate), will tell us how far we should count outwards from 0 (The Origin). The second term, y (called the y-coordinate), will tell us how far we will count outwards from our x coordinate.
I hope this helps! If you would like me to elaborate more just let me know:)
