Alvin is 5 years younger than elsa. the sum of their ages is 93. what is elsas age

Answers

Answer:

Step-by-step explanation:

Given:

Alvin is 5 years younger than Elsa, and the sum of their ages is 93.

Let x represent Elsa's age, so Alvin's age would be x - 5 because he is 5 years younger.

x + x - 5 = 93

Add like terms.

2x - 5 = 93

Add 5 to both sides.

2x = 98

Divide both sides by 2.

x = 49
