Step-by-step explanation:
Based off the typical rules of integers, expressions like these can be simplified to look different but mean the same thing.
In this case, we subtracted a negative value from a positive value; by doing this, we actually added positive 4.
Based on the same principals, adding a negative number is equivalent to subtraction!
Any time you see equations similar to this, you want to cancel out the 2 negative signs to make it positive!

Answer:
The vector parallel to the line of intersection of the planes given by the equations
2x−3y+5z=2 and 4x+y−3z=7
is (x, y, z) = (23/14, 3/7, 0)
Where z is a free variable.
(B) The equation of the plane through the point (4,5,6) and perpendicular to the line of intersection of the planes
2x−3y+5z=2 and 4x+y−3z=7
is 2x + 13y + 7z = 115
