# Triangle and parallelogram in the space

Level pending

Area of triangle formed by $$\overline{a_1}=(3,1,2), \overline {b_1} = (3,-5,5)$$ is equal to the area of the parallelogram formed by $$\overline{a_2} = (4,7,3), \overline{b_2}=(4,6,x)$$. Let $$y_1$$ and $$y_2$$ are the possible values that satisfy $$x$$. What is the value of $$\lfloor y_1+y_2 \rfloor$$?
