Let the cost of senior citizen ticket be x and cost of child ticket be y
ATQ,
![\sf \qquad 3x + y = 38 \\ \sf \qquad3x + 2y = 52](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad%203x%20%2B%20y%20%3D%2038%20%5C%5C%20%20%5Csf%20%5Cqquad3x%20%2B%202y%20%3D%2052)
<h3>Solve the equation for x and y</h3>
![\sf \qquad \: 3x + y = 38 \\ \sf \qquad - 3x - 2y = - 52](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad%20%5C%3A%203x%20%2B%20y%20%3D%2038%20%5C%5C%20%20%5Csf%20%5Cqquad%20-%203x%20-%202y%20%3D%20%20-%2052)
![\sf \qquad y = 14](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad%20%20y%20%3D%20%20%2014)
Substitute the given value of y into the first equation
![\sf \qquad3x + 14 = 38](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad3x%20%2B%2014%20%3D%2038)
![\sf \qquad3x = 38 - 14](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad3x%20%20%3D%2038%20-%2014)
![\sf \qquad3x = 24](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad3x%20%3D%2024)
![\sf \qquad \: x = 8](https://tex.z-dn.net/?f=%20%5Csf%20%5Cqquad%20%5C%3A%20x%20%3D%208)
<em>Therefore, The cost of 1 senior citizen ticket is </em><em>8</em><em> </em><em>d</em><em>o</em><em>l</em><em>l</em><em>a</em><em>r</em><em> and cost of 1 child ticket is 14</em><em> </em><em>d</em><em>o</em><em>l</em><em>l</em><em>a</em><em>r</em><em>...~</em>
