Question

when
A line is passing through the point of intersection of the lines 2x - y = 4 and x + 3y = 9)
and parallel to y-axis. Find the equation of line.

Answer 1

Answer:

x = 3

Step-by-step explanation:

2x - y = 4 .... (1)

x + 3y = 9 .... (2)

3 × (1) + (2)

6x - 3y = 12

x + 3y = 9

7x = 21 ⇒ x = 3  equation of the line passing through (3, 2) and ║ to y-axis.

(21/7) + 3y = 9 ⇔ 21 + 21y = 63 ⇒ y = 2

(3 , 2)
