RSM homework lol
made equation, then solved it.
hope this helps!
Well, if
{bx - 6y = 18 and {2x - 3y = 9, you might want to try elimination
Multiply second equation by -2: bx - 6y = 18 and -2(2x - 3y = 9)
Simplified: bx - 6y = 18 and -4x + 6y = -18
Now if you add them you get: -4x + bx = 0
Then simplified: bx = 4x
divide by x: b = 4
Your final solution is b = 4.
Hope that helps!
Answer:

We have been given that on Thursday, three times as many adult tickets as child tickets were sold. We can represent this information in an equation as:

We have been given that at a the movie theater, child admission is $6.10 and adult admission is $9.20.The all tickets were sold for a total of $707.70. We can represent this information in an equation as:
