Math 100 - Number Problem

1. Group II

2.  the point of these problem
isn't their relation to "real life",
but your ability to extract the
math from the English word.

3. If 4 is added to 3 times a
number, the result is 58.
What is the number?

4. Solutions :
3x+4=58
3x+4-4=58-4
3x=54
3 3
x=18

6.  When 6 times a number is
increased by 4, the result is
40. Find the number.

7.  First, let x stand for the number
gives the equation
6 x + 4 = 40
6x= 40-4
6 x = 36
6 6
X= 6 is the Answer 
When 6 times a number is increased by 4,
the result is 40. Find the number.

8.  One number exceeds another
number by 5. If the sum of the
two numbers is 39, find the
smaller number.
Now, let the smaller number be
x. Therefore, the larger number
equals x + 5. Now, use the
problem to set up an equation.

9.  If the sum of two numbers is 39
x+(x+5)=39
2x+5=39
2x+5-5= 39-5
2x=34
2 2
X=17
One number exceeds another number
by 5. If the sum of the two numbers is
39, find the smaller number.
