Question 13638: x+(x-10)+1/2x=180
to solve this problem we will use simple algebra
that is
x+x-10+1/2x=180
2x+1/2x=180+10
taking lcm
(2x(2x)+1)/2x=190
(4x^2+1)/2x=190
by cross mutiplication
4x^2+1=190*2x
4x^2+1=380x
4x^2-380x+1=0
now we can do it either by qudratic formula
or completing square method
