Question

Coffee $\left(\$x\right)$ and tea $\left(\$y\right)$have a two-dollar difference in prices.
Which of the following equation represents the above statement?

• A. $\text{x}-\text{y}=2$
• B. $\text{2x}-\text{y}=1$
• C. $\text{x}-\text{2y}=1$
• D. $\text{x}+\text{y}=-2$

Answer 1

The correct option is A $\text{x}-\text{y}=2$

Let the price of coffee be $$\text{x}$ and the price of tea be $$\text{y}$ respectively.

According to the question statement
Coffee price - Tea price = $2$
$\text{x}-\text{y}=2$
So,
$\text{x}-\text{y}=2$, represents the linear equation in two variables of the given statement
