X + 2y = 3 ----------- (1)
x - y = 6 ------------(2)
Equation (2) - (1) :
-3y = 3 // ║x - x = 0 ║;║ - y - 2y = -3y║ ; ║6 - 3 = 3 ║
y = -1 // ║ ÷ (-3) on both sides ║
Substitute y = -1 into equation (2) :
x - y = 6 // ║ Equation 2║
x - ( -1 ) = 6 // ║ Sub y = -1 into the equation║
x + 2 = 6 // ║ open the bracket ( - ) ( -) = + ║
x = 4 // ║ Take away 2 from both sides║
Answer: x = 4, y = -1

This is the construction of a perpendicular line to the given line AB using a point F, which does'not lies on the line AB.
The first two steps are constructed. We have to give the next two steps to complete the construction.
Step 3: Using the same radius A and B as centers, draw two arcs below the line AB.
Step 4: The two arcs will intersect at a point. Name that point as 'X'. Join 'F' and 'X'.
Thus, FX is the required perpendicular to the line AB from point 'F'.
