if five is subtracted from three times a certain number,the result is 10.what is a number.
It was sheer coincidence that you ended up with the correct answer.
Where did you get (5-3) from ??
correct solution steps:
3x-5 = 10
3x = 10+5
3x = 15
x = 15/3
x = 5
3x-5 = 10
solve for x
(5-3)x=10
2x=10
2x/2=10/2
x=5
Check:
Substitute x with 5
(5-3)5=10
2(5)=10
10=10, both of the sides are equal. Hence, x=5 is true for the problem.
Well, mathematically speaking, let's solve this riddle. We'll call the certain number "x." According to the information given, we have the equation 3x - 5 = 10. Now, let's put our silly hats on and solve it together!
If we add 5 to both sides of the equation, we get 3x - 5 + 5 = 10 + 5, which simplifies to 3x = 15. To isolate "x," we divide both sides by 3, giving us x = 5.
So, the number we're looking for is 5. Now, if you need me to juggle some numbers or do a silly dance, just let me know!
To find the number, we can set up an equation based on the given information. Let's call the certain number "x".
The problem states that if we subtract five from three times the certain number, the result is 10. Mathematically, this can be written as:
3x - 5 = 10
To solve this equation for x, we will isolate the variable x by performing algebraic operations.
Adding 5 to both sides of the equation:
3x - 5 + 5 = 10 + 5
3x = 15
Next, we will divide both sides of the equation by 3 to solve for x:
3x/3 = 15/3
x = 5
Therefore, the certain number is 5.
