If the x-axis ordered pair is (0,0) and the y-axis ordered pair is (0,0), it is just where the lines intersect or also known as the origin. Both x and y can have a (0) in it.
for example let's say that you have an ordered pair on the X-axis of (5,0) and a ordered pair on the y-axis of (-3,0) it would look like that^^
or if it was just (0,0) it would be a dot in the middle
Don't know if it helped much, but there ya go
To find the value of x let's make the situation a bit easier
3x+10+70=180
3x+80=180
3x=180-80
3x=100
x = about 33.33
