Question

{4x - 2y = 12 {20x - 10y = 60 (tiger Algebra)

Answer 1

infinite number of solutions

Explanation:

given the 2 equations

4x - 2y = 12 → (1)

20x - 10y = 60 → (2)

note that (2) is 5 × (1) , that is

5(4x) - 5(2y) = 5(12)

20x - 10y = 60

thus (1) and (2) are the same equation and will have an infinite number of solutions.
