Let the number be x
By the problem,
10-5x=3x
-5x-3x= -10
-8x= -10
x= -10/-8=5/4=1 1/4
Therefore,the number is 1 1/4

A Number Subtracted From 10
2016-11-06 21:09:15 · answer #2 · answered by yun 4 · 0⤊ 0⤋
Hi,
For this question, we need to convert the words presented in English into mathematical symbols and numbers that can form an equation.
Therefore, we see that they are telling us that 5 times a number (let's call x) is being subtracted from 10. Therefore, we have the following:
10 - 5x
Now, this is all equal to 3 times this number or triple x:
10 - 5x = 3x
At this point in the problem, they probably would like us to solve for x alone by adding 5x to both sides of the equation to get:
10 = 8x
Now, let's isolate for x alone by dividing both sides of the equation by 8 to get:
x = 10 / 8
Now simplify that fraction noticing that a common factor of 2 can be pulled out of the numerator and denominator to get:
x = 5 / 4 <==== FINAL ANSWER
I hope that helps you out! Please let me know if you have any other questions!
Sincerely,
Andrew

Let the no be x.
Then 5x.
subtracted from 10= 10-5x=3x.
10=8x. x= 10/8= 5/4.

For this to be the case, five times the number plus three times the number, must be 10. Thus eight times the number is 10, hence the number is 10/8=5/4.

5/4 or 1.25: 10-5x=3x; 10=8x; 10/8 or 5/4=x

10 - 5x = 3x
10 = 8x
x = 10 / 8
x = 5 / 4

10-5x=3x
3x=10-5x
3x+5x=10
8x=10
x=10/8
x=1.25

10-5x=3x
10-5x+5x=3x+5x
10=8x
10/8=x
5/4=x

10 - 5x = 3x . . . . .add 5x to both sides
10 = 8x . . . . . . . . .divide both sides by 8
1.25 = x
