**x = price of child's admission ticket**

**2x = price of adult's admission ticket**{price of adult is twice the price of child}

2(2x) + 2x = 12.60 {2 adults and 2 children cost $12.60}

4x + 2x = 12.60 {multiplied 2 by 2x}

6x = 12.60 {combined like terms}

x = $2.10 {divided each side by 6}

price of child's admission ticket is
