There are 12 more toy cars than toy trucks in a toy box with a total of 38 toy cars and trucks. How many toy trucks are in the toy box?
T+T + 12 = 38
2T +12 = 38
38-12 = 26
2T = 26
2/26 = 13
T = 13
Step One
Toy Trucks = x
Toy Cars = x+12 (because there are 12 more toy cars than toy trucks in a toy box)
Total total of toy cars and trucks = 38
Step Two
equation = x + x + 12 = 38
2x + 12 = 38
Step Three
Keep 2x as it is but use 12 to - (minus) from +12 and 38
Which will look like this
2x + 12 = 38
-12 -12
The 12 after 2x automatically get canceled out because they are same numbers.
What remains is 2x = 26 (just to show you calculation 38-12 =26)
Step three
x = 26
----- (divide)

Answer is 13
t + t + 12 = 38
2t = 26
t = _____ trucks
To find the number of toy trucks in the toy box, we need to set up and solve an equation.
Let's assume that there are x toy trucks in the toy box. According to the problem, there are 12 more toy cars than toy trucks.
The number of toy cars can be written as: x + 12.
Since the total number of toy cars and trucks is 38, we can set up the equation:
x + (x + 12) = 38
Now, let's solve this equation for x.
Combining like terms, we have:
2x + 12 = 38
Subtracting 12 from both sides of the equation, we get:
2x = 26
Dividing both sides by 2, we find:
x = 13
Therefore, there are 13 toy trucks in the toy box.
