90 -t = 10
10t = 90
10 + 90 = t
9t = 90
The required equation for the tickets Molly buys is 10t = 90.
An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Price of one ticket bought by Molly = $10,
Also,
Amount spent by Molly on tickets = $90.
To find the equation,
Let Molly buys t concern tickets,
Since, the price of one ticket is $10,
Total price for tickets = 10t
The total amount is $90,
So, the equation can be written as,
10t = 90

Answer:
24 and 30
Step-by-step explanation:
The sum of two numbers is 54. Let's use the variables x and y to represent theses numbers:
x + y = 54
The smaller number is 6 less than the bigger one. Let's say that x is the smaller number and y is the bigger number:
y - 6 = x
Now we know that x is equivalent to y - 6. So, let's replace x with y - 6 in the original equation:
x + y = 54
y - 6 + y = 54
Combine like terms:
2y - 6 = 54
Now we can solve for y:
2y - 6 = 54
Add 6 to both sides of the equation to isolate the 2y:
2y = 60
Divide both sides by 2 to find the value of y:
y = 30
Now that we know the value of y, we can solve for x:
y - 6 = x
30 - 6 = x
24 = x
The value of the two numbers is 24 and 30.
