Parker · Answer

Step-by-step explanation:     x- cost for an adult  y- cost for a child    2x + y = 3900  3x + 2y = 6300  Multiply 1st equation by 2    4x + 2y = 7800                             ( - )   3x + 2y = 6300  -----------------------  x + 0y = 1500  ------------------------  x = 1500    2x + y = 3900  y = 3900 - 2x    sub x=1500    y = 3900 - 2 (1500)   y = 3900 - 3000  y = 900    cost for an adult = 1500  coat for a child = 900
