Algebraic expression

Algebraic expression

adding = t+ 17
see the t could be any number so you would have to make it that
the person doing the equation would know what the number is. 
so it could be
5+17   now write it in a algebraic expression
t+17= 22

so with every equation you don't use only use numbers
u will often use letters.
cause why not.

yes I understand this type of maths
