4. During a bowling tournament, Tyler scored x strikes and y spares. Lucy scored a strikes and b spares. What is the best interpretation of the following equation in everyday language? 2x + 4 = a Lucy scored 4 strikes more than twice the number of strikes Tyler scored. Lucy scored 4 spares more than twice the number of strikes Tyler scored. Tyler scored 4 spares

What a horrible question. "the best interpretation" - How could anyone possibly know that? "everyday language" - This is not well-defined.

Directrix (directrix):

a represents Lucy's number of strikes x represents Tyler's number of strikes 2x + 4 = a 2 times Tyler's number of strikes plus 4 equals Lucy's number of strikes. The question is poorly written. Hazarding a guess, Lucy's number of strikes equals 2 times Tyler's number of strikes plus 4 (strikes). @CrisYB
