X-7=18
+7 to both side
X=25

hello!

Let the number be n.

Now, "seven less than a number" means we subtract 7:-

n-7

This expression is equal to 18:-

[tex]\sf{n-7=18}[/tex]

[tex]\mathcal{SOLUTION:-}[/tex]

  • Add 7 to both sides:-

[tex]\bigstar{\boxed{\pmb{n=25}}}[/tex]

note:-

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
