Makutano ya kushoto kabisa iko kwenye mstari wa mteremko 2 kupitia asili, ambayo ni y2x. Kutatua 2x1.8 hutoa x0.9.Makutano ya kati yapo kwenye mstari wa mteremko -1 kupitia 2,1, ambayo ni y-x3. Kutatua -x31.8 hutoa x1.2.Makutano ya kulia kabisa yapo kwenye mstari wa mteremko 2 hadi 2,1, ambayo ni y2x-3. Kutatua 2x-31.8 hutoa x2.4.Kwa hivyo, jumla ya viwianishi vitatu vya x-ni 0.91.22.44.5.
