$\\ \sf\longmapsto 0.9(7x+14)=1.5-(x+2)$

$\\ \sf\longmapsto 6.3x+12.6=1.5-x-2$

$\\ \sf\longmapsto 63x+12.6=-x-0.5$

$\\ \sf\longmapsto 63x+x=-0.5-12.6$

$\\ \sf\longmapsto 64x=-13.1$

$\\ \sf\longmapsto x=\dfrac{-13.1}{64}$

$\\ \sf\longmapsto x=0.2$

Use the identity x^3+y^3+z^3−3xyz=(x+y+z)(x^2+y^2+z^2−xy−yz−zx) to determine the value of the sum of three integers given:

RoseWind [281]

Inserting all the given information into the identity, we have

$684-3(210)=(x+y+z)(110-107)\implies x+y+z=18$
