Short Answer TypeThe given equation is
2x = y ⇒ 2x – y
⇒ 2x – y + 0 = 0
Comparing with ax + by + c = 0, we get
a = 2
b = –1
c = 0
This equation has infinitely many solutions.
Write each of the following as an equation in two variables:
(i) x = – 5 (ii) y = 2
(iii) 2x = 3 (iv) 5y = 2.
Which one of the following options is true, and why?
y = 3x + 5 has
(i) a unique solution,
(ii) only two solutions,
(iii) infinitely many solutions.
