If 10 will be added to four times to a certain number, the result is 5 less than five times the number, what is the number?
Let the number be x
“10 is added four times” → x + 40
“5 less than five times the number” → 5x − 5
So, equation becomes:
x + 40 = 5x − 5
x + 40 = 5x − 5
40 + 5 = 5x − x
45 = 4x
x = 45 ÷ 4
x = 11.25
The number is 11.25
