Given:
The sum of 9 times a number and 7 equals 5.
The objective is to translate the sentence into an equation.
Consider the unknown number as b.
9 times of a number means, 9 multiplied by that unknown number. It can be written as 9b.
And it is given that the sum of this 9b and 7 is equal to 5.
So add 7 to the 9b.
[tex]9(b)+7=5[/tex]Hence, the required equation is obtained.
