12
T+T + 12 = 38
2T +12 = 38
38-12 = 26
2T = 26
2/26 = 13
T = 13
2T +12 = 38
38-12 = 26
2T = 26
2/26 = 13
T = 13
how did you get 26
ANSWER: 26
12 toy cars
26 toy trucks
38 total toy cars and trucks in box
12 toy cars
26 toy trucks
38 total toy cars and trucks in box
What do the two T’s represent?
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)
