hunter is 4 years older than his sister Elisabeth.if the sum of their ages is 18 how old is hunter
sister's age --- x
Hunter's age = x+4
x + x+4 = 18
2x = 14
x = 7
the sister is 7 and Hunter is 11
check: is the sum of their ages equal to 18 ? YES
is Hunter 4 years older than the sister ? YES
this is the first and last time i will ever say this but math helper is right
To solve this problem, we can set up an equation based on the given information. Let's assume Hunter's age is represented by "H" and Elizabeth's age is represented by "E".
We know that Hunter is 4 years older than Elizabeth, which can be stated as:
H = E + 4
Additionally, the sum of their ages is given as 18:
H + E = 18
Now we can solve this system of equations to find the values of H and E.
Substituting the value of H from the first equation into the second equation, we get:
(E + 4) + E = 18
2E + 4 = 18
Next, we can simplify the equation:
2E = 18 - 4
2E = 14
Dividing both sides of the equation by 2, we obtain:
E = 7
Thus, Elizabeth is 7 years old.
To determine Hunter's age, we substitute the value of E back into the first equation:
H = E + 4
H = 7 + 4
H = 11
Therefore, Hunter is 11 years old.
