Answer :
We are given that "15 less than a number is 22." This means that if we let [tex]$x$[/tex] represent the number, the expression "15 less than a number" is written as:
[tex]$$
x - 15
$$[/tex]
Since this is equal to 22, we have the equation:
[tex]$$
x - 15 = 22
$$[/tex]
To find [tex]$x$[/tex], we add 15 to both sides of the equation:
[tex]$$
x - 15 + 15 = 22 + 15
$$[/tex]
This simplifies to:
[tex]$$
x = 37
$$[/tex]
Thus, the correct choice is:
A. [tex]$\; x-15=22$[/tex] and [tex]$\; x=37$[/tex].
[tex]$$
x - 15
$$[/tex]
Since this is equal to 22, we have the equation:
[tex]$$
x - 15 = 22
$$[/tex]
To find [tex]$x$[/tex], we add 15 to both sides of the equation:
[tex]$$
x - 15 + 15 = 22 + 15
$$[/tex]
This simplifies to:
[tex]$$
x = 37
$$[/tex]
Thus, the correct choice is:
A. [tex]$\; x-15=22$[/tex] and [tex]$\; x=37$[/tex].
