<h3>lets create equation first then to solve it</h3>
.
Step-by-step explanation:
5+8+a=20
<h3>lets solve it.</h3>
5+8+a=20
13+a=20
a=20-13
a=7.
<h3>maybe it will be correct.</h3>
234 = a + s s = students a = adults
2a = s
after you get the equations you solve. plug 2a into the above equation.
so u get
234 = a + 2a
234=3a then divide 3 from each side
78 = a
so 78 adult tickets were sold
