Wilma and Betty are playing a number game. Wilma tells Betty, "I'm thinking of a number between 1 and 10. If I take the number a
nd add 4 to it and then multiply that by 3, I get 30." What number is Wilma thinking of?
1 answer:
Just work this problem out backwards. First write out an equation.
(x+4)•3=30
Now solve :
(x+4)•3=30
3x+12=30
-12 -12
3x=18
/3 /3
x=6
Your answer is 6!
