The equation is 65 - 8 = x and the solution for x would be 57.
You won the game, due to your score of 137 and your friend's 130,
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that
Your friend's score is 65, and your score of x is 8 less than your friend's,
You would subtract that in order to determine the variable because you have less than your friend.
So the equation is: x = 65 - 8 = 57.
Given that
Your friend's score doubles
So 2 × 65 = 130.
Your score increases by 80 points by the game's end.
So 57 + 80 = 137.
You won the game, due to your score of 137 and your friend's 130,
