Name your unknown
a= number of adult ticket 
c= number of kid ticket

6a + 4c = 1590
a + c = 321
Solve for a and c by using substitution
a= 321-c
now substitute 
6(321-c) + 4 c = 1590
1926 - 6c + 4c = 1590
1950 - 1590 = 6c -4c
336 = 2c
336/2 = 2c/2
c= 168

a + c = 321
a+ 168 = 321
c= 321-168 = 153
