Hi!
So we have to make a system of equations here.
Let sibling 1 be O and sibling 2 be Y (for older and younger)
So:
O + Y = 64
O = 64 - Y
(Either one works)
The older sibling is 6 years older.
O = Y + 6
Make everything in terms of Y.
64 - Y = Y + 6
Same to both:
58 = 2y
2y = 58
Divide by 2 on both sides:
y = 29
Since the older sibling is 6 years older:
29 + 6 = 35
Y = 29
O = 35
Let me know if you have any questions.

Ax + bx = c
<u>Step 1: Solve for </u><em><u>x</u></em>
- Factor: x(A + b) = c
- Isolate <em>x</em>: x = c/(A + b)
We know that we cannot divide by 0, so A + b cannot equal 0.
