Answer:

Hey there!

3x+y=7

2x+y=6

3x+y=7

-2x-y=-6

Add these two equations vertically so the y terms cancel out (this is known as the elimination method)

x=1

3x+y=7

3(1)+y=7

3+y=7

y=4

(x=1, y=4)

Hope this helps :)

how do you use absolute value to find the distance between two points that have the same X-coordinates but different Y-coordinat

sdas [7]

So since x coordinates are same, we just have a horizontal distance to find (no fancy slanted lines)

so what you do is
|y1-y2|=distance
