Answer:
Step-by-step explanation:
n-(7+n) which is a strange problem to give you as that is equal to
n-7-n which always equals -7
And that means n can be any real number and the expression still equals -7
The algebraic expression will be -7. x is the assumed algebraic expression. The equation is solved by subtraction.
An algebraic expression is a phrase that has been combined using operations like addition.
Let n is the number and x be the solution for the given condition;
If the number is decreased by 7 then the equitation will be (n-7).
From the given condition;
[tex]\rm x=\rm n-(n-7) \\\\ x=n-n-7 \\\\ x=-7[/tex]
Hence the algebraic expression will be -7.
