Answer: Eli’s age is 24 years and Cora’s age is 74 years
Step-by-step explanation:
To find Eli’s age and Cora’s age, use the following condition.
Eli’s age is represented by term ‘x’
Cora’s age is represented by term ‘3x + 2’
x + 3x + 2 = 98
Add x and 3x
4x + 2 = 98
Subtract 2 from both sides
4x = 96
Divide by 4 on both sides
x = 24
Therefore Eli’s age is 24 years
To find Cora’s age, plug in 24 for x
3(24) + 2 = 72 + 2 = 74
Answer:
Cora is 74 years old
Eli is 24 years old
Step-by-step explanation:
Cora’s age = x
Eli’s age = y
x = 3y + 2
x + y = 98
x = 98 - y
98 - y = 3y + 2
98 - 2 = 3y + y
96 = 4y
24 = y
x + 24 = 98
x = 98 - 24
x = 74
