Question

What is the solution of the equation: $5x+10y=35?$

• A. $(1,3)$
• B. $(3,2)$
• C. $(5,1)$
• D. Infinite pair of values of $x$ and $y$

Answer 1

The correct option is D

Infinite pair of values of $x$ and $y$

The equation simplifies to $x+2y=7$. We can have many values that satisfies this equation. For example, $(1,3),(5,1),(3,2)$ etc. Therefore a linear equation in two variables has infinite number of possible solutions.
