Can someone me with this problem ?

senior tickets sold: 12

child tickets sold:8

Step-by-step explanation:

Let

x= amount of senior tickets sold

y= amount of child tickets sold

For the first equation, it should look like:

200=14x+4y

For the second equation, it should look like:

92=7x+y

So this is a systems of equations problem. So I will use substitution as it is easier:

1.) Take one of the equations (in this case ill take 92=7x+y) and make one variable have a value, in this case ill isolate the y.

2.) Take the value of y and plug it into "y" into the other equation to solve "x"

(editor's note:instead of dividing it by 14, I multiply by 1/14 as it would look complicated in the equation solving steps)

3.) Then plug the value of "x" to one of the equations to solve for "y" (which I'll use the 92=7x+y)
