Write the system of equation based on the problem
"A total of 345 tickets that consists of adult tickets and students ticket were sold" could be written as:
∴ a + s = 345 <em>(first equation)</em>
"<span>the number of student tickets sold was two times the number of adult tickets sold" could be written as:
</span>∴ s = 2a <em>(second equation)</em>
<span>
Solve the system of equation
Substitute 2a as s in the first equation
a + s = 345
a + (2a) = 345
3a = 345
a = 345/3
a = 115
There are 115 adult tickets sold.</span>

Answer:
3x + 4 = 12
Step-by-step explanation:
plus = +
equal = =
but if you were looking for the answer to the equation
3x + 4 = 12
3x = 12 - 4 (the symbol changes bc i switched it to the other side)
3x = 8
x = 8/3
