Two planes that intersect are simply called a plane to plane intersection. When they intersect, the intersection point is simply called a line.
Therefore, Plane R and Plane S form a line when they intersect.
First you need to use the distributive property: 27(x+4)=-6
27x+108=-6
then you need to subtract 108 from -6 to
get x alone. 27x= 102
Lastly divide 102 by 27 to finally get x alone: x=3.777
the answer would be: x= 3.77 or 3.8
