12-(x+3)=10
Simplify the equation.
12-x-3=10
Combine like terms.
(12-3)-x=10
Simplify.
9-x=10
Subtract 9 from both sides to get x by itself.
-x=1
Divide both sides by -1 to get x by itself.
x=-1

Step-by-step explanation:
I wrote down the equation and how to get the answers here:
Answer: Children = 108
Adult = 52
Step-by-step explanation:
Let x = number of children
Let y = number of adult
Based on the information given, we can form an equation which will be:
x + y = 160 ........ i
2x + 5y = 476 ........ ii
Multiply equation i by 2
Multiply equation ii by 1
2x + 2y = 320 ....... iii
2x + 5y = 476 ........ iv
Subtract iii from iv
3y = 156
y = 52
Number of adults = 52
Since x + y = 160
x + 52 =160
x = 160 - 52
x = 108
Number of children = 108
It was proven that there is infinite number of prime number. So you can't find the biggest (because always be bigger one)
