Question

if five is subtracted from three times a certain number,the result is 10.what is a number.

Answer 1

3x-5 = 10

solve for x

Answer 2

(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.

Answer 3

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
