If you are solving for a value, you can divide by -1
For example:
-x=5 (divide by -1)
x=-5
If you have an equation, you can negate every part
For example:
-x^2-2x+7=0 (negate)
x^2+2x-7=0
Answer:
180-63= 117

Santosh must sell the remaining dotpens with a surplus of 40 % to gain 10 % on the whole.
<h3>How to calculate the gain of selling dotpens</h3>
We know that Santosh sold 200 dotpens with a loss of 5 % and he must sell the remaining dotpens with an unknown surplus in order to obtain 10 % of the whole. The situation can be represented by the following expression:

The function of the line would be best represented by y=mx+b where m = slope and b = y intercept.
To find this we can put it into the slope-intercept form of y-y1=m(x-x1)
Which is:
y-8=2(x+12)
y=2x+24+8
y=2x+32
Hope that helps!
