I don't really understand your question, but it think it goes like this:
x-17-20=180
gather common terms
x-37=180
move 37 to other side
x=180+37
addition
x=217
he would have to work 163 weeks
Step-by-step explanation:
here,
x1= -5. x2=4
y1= -22. y2=r
slope(m)=3
now we have,
m=(y2-y1)/(x2-x1)
or,3=(r-(-22))/(4-(-5))
or,3=(r+22)/(4+5)
or,3=(r+22)/9
or,27=r+22
or,r=27-22
or,r=5
Let breadth be x
We know
It doesnot have any real roots
