Answer:
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
Step-by-step explanation:
<u>First, we need to establish a system of equations:</u>
x= number of adults tickets
y= number of senior citizen tickets
x + y= 400
6x + 3y= 2,070
<u>Now, we isolate x in one equation and substitute the value in the other:</u>
x= 400 - y
6*(400 - y) + 3y = 2,070
2,400 - 6y + 3y = 2,070
330 = 3y
110 = y
Number of senior citizen tickets sold= 110
Number of adults tickets sold= 290
<u>Prove:</u>
290 + 110= 400
6*290 + 3*110= 2,070

Answer:
The answer is 4.
Step-by-step explanation:
This is a basic one-step algebra problem.
We have: 3x = 12.
We would like find what x equals. In order to do that, we must have the x variable on one side of the equals sign, and the rest of the numbers on the other side. In other words, we have to isolate the x variable away from its coefficient.
To do this, we must divide BOTH sides of the equation by 3. This would mean that the 3 on the left side of the equals sign cancels out, totally getting rid of the 3.
Here's what it should look like:
Now, we actually divide both sides now, which should look like this:
This is because 3 divided by 3 is 1, and 12 divided by 3 is 4.
Hence, our solution for x is 4. Hope this helped!
