Answer:
x + y = 5
Step-by-step explanation:
For point of intersection: when x + y - 5 = 0 and 2x - y + 4 = 0 meet is the point when both x(s) are and both y(s) are same. Adding both:
x + y - 5 = 0
2x - y + 4 = 0
3x - 1 = 0 ⇒ x = 1/3
Thus,
x + y - 5 = 0 ⇒ y = 5 - (1/3) = 14/3
Point of intersection is (x , y) = (1/3 , 14/3)
Using intercept form: (intercepts are same ⇒ a = b)
equation is x/a + y/b = 1
⇒ x/a + b/a = 1 [a = b]
⇒ x + b = a
⇒ 1/3 + 14/3 = a
⇒ a = 5
∴ Equation is x + b = a
x + y = 5
