Lets x = # of hours Melania works at <span>office clerk
and y = </span># of hours Melania works as a <span>cashier
x + y = 38 so x = 38 - y
13x + 9.25y = 434
substitute </span> x = 38 - y into 13x + 9.25y = 434
13x + 9.25y = 434
13(38 - y) + 9.25y = 434
494 - 13y + 9.25y = 434
-3.75y = -60
y = 16
x = 38 - y so x = 38 - 16 = 22
answer
Melania works at office clerk = 22 hours
Melania works as a cashier = 16 hours
