6.50(XXXX-A) + X.XXX = 8,444 Then, use XXXXXXXXXXXX property:
6,XXX - X.50A + X.50A = X,XXX XXXXXXXX X.XXX XXXX X.XXX, XXX subtract X,500 from either side:
3.00A=X,444-X,XXX XXXXXXXX:
3A = XXXX XXXXXX by X:
A = 648
XXXXXXXXX, XXX adult XXXXXXX were XXXX. XXXX plug this value of A into XXX XXXXX equation XX XXXX X, the XXXXXX XX child XXXXXXX.C + X = 1,XXX
X + XXX = X,000
Therefore, X = 352.
