George is 3 years old
Step-by-step explanation:
Three times Heidi's age plus two times Georges age equals 51
Heidi's age is also five times George's age
Assume that George's age is x
Use the information to solve the problem
∵ 3(5x) + 2(x) = 51
- Simplify it
∴ 15x + 2x = 51
∴ 17x = 51
- Divide both sides by 17
∴ x = 3
∵ x represents George's age
∵ x = 3
∴ George's age is 3 years
George is 3 years old
