Eric is twice as old as his brother Lucas. If 4 is subtracted from Eric's age and 4 is added to Lucas age, their ages will be equal. What are the boys' ages now?

You are given this

Eric is twice as old as his brother Lucas soo E = 2L

you are given this too

If 4 is subtracted from Eric's age and 4 is added to Lucas age, their ages will be equal.

sooo E-4 = 4+L

Let's put in E = 2L into the second equation

2L-4 = 4+L now subtract 'L' from both sides

L -4 = 4 Now add 4 to both sides of the equation

L = 8 This is Lucas' age

E = 2L = 2(8) = 16 Eric's age
