Let ordered pairs
X Y
-1 1
-2 2
-3 3
-4 4
-5 5
<span> What kind of figure do you get?
For this case a straight line was obtained, whose equation is
</span><span> y = -x
</span><span> In what quadrants does the figure lie?
The figure is in the second quadrant. (See graphic)
</span>
To work out do the inverse
253+326
579
Then check it by doing 579-326
=253
Y=579
It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
Logic.
The value of x in the equation 
is x=(7+3
)/2,
(7-3)/2.
Given equation .
We have to find the solution of the equation.
Equation is solved to find the value of variables. The number of values of the variable depends on the highest power of variables.
let (x-5)=u-------------------1
equation becomes 
solution of a quadratic formula
x=-b±
/2a
on comparing with general form a=1,b=3, c=9
u=-3±
=-3±
=-3±
=-3±

, 
=-3-3
put the values of 
in equation 1
x-5=
x-5=-3+
x=-3+3
x=7+3
put the values of in equation2
x-5=
x-5=-3-3
x=7-3
Hence the values of x are 7+3
, 7-3.
