I would solve the first equation for x and then sub that value into x in the second equation. That's the easiest way. x - 2y = 3 solved for x is x = 2y+3. Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2. 13y = -13, and y = -1. Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1. Therefore, your solution to this system is (1, -1), first choice above.
A mapping system is a way of describing
a C. Preimage of a figure. Mapping statements are known to define the range of
data sources thus showing all the data. While on the other hand, preimage (in
Mathematics) meaning is that set of all the elements of the domain that maps to
the members of S.

Answer:
or 
Step-by-step explanation:
The perpendicular slope is the opposite-reciprocal of the original slope:
Perpendicular slope of -2 is 
Write the equation in point-slope form (
):
Convert to slope-intercept form if needed:
