Question

If Lionel Messi $\left(x\right)$ scores twice as many goals as Cristiano Ronaldo $\left(y\right)$ in a single La Liga season. Which of the following statements is true if both players scored $76$ goals in the same season?

• A. $x+y=76$
  $2x=y$
• B. $x-y=76$
  $2x=y$
• C. $x-y=76$
  $x=2y$
• D. $x+y=76$
  $x=2y$

Answer 1

The correct option is D $x+y=76$

$x=2y$
Let's say Linoel Messi's goals are $x$, and Cristiano Ronaldo's goals are $y$.
Case 1:
Messi's total goals $=2\times$Ronaldo's goals
Linear equation in two variables will be
$\Rightarrow x=2y$

Case 2: It is given that they scored total $76$ goals
Hence, goals made by Messi $+$ Goals made by Ronaldo$=76$
Linear equation in two variables will be
$\Rightarrow x+y=76$
