Respuesta :
The number will be [tex]15[/tex] .
What is expression ?
Expressions is a finite combination of symbols that is well-formed according to rules that depend on the context.
We have,
Let a number [tex]=x[/tex]
So,
Write [tex]5[/tex] times a number is increased by [tex]10[/tex] in [tex]x[/tex] form,
i.e. [tex]5x+10[/tex]
And,
Write [tex]100[/tex] is decreased by the number in [tex]x[/tex] form,
i.e. [tex]100-x[/tex]
So,
According to the question,
[tex]5x+10=100-x[/tex]
Now simplify the above expression,
i.e.
[tex]5x+x=100-10[/tex]
[tex]6x=90[/tex]
[tex]x=15[/tex]
So, the number is [tex]15[/tex].
Hence, we can say that the number will be [tex]15[/tex] .
