How do you write \[8\] increased by \[3\] times a number as an algebraic expression?

Hint: We have to write a algebraic expression from the words a algebraic expression is a mathematical phrase that contains a combination of numbers, variables and operational symbol. Write an equation to represent the situation given in the problem then define your variable and solve them using a basis for converting this.

Complete step by step solution:
\[8\] increased by \[3\] times a number we have given this we have to convert this into algebraic expression let the number be represented by \[x\] then three times a number\[:3\times n\] as we know times in the algebraic equation represent as multiplication so three time a number is \[3n\] and increased by eight means adding eight.
So the equation will become \[3n+8.\]
This is the conversion of the words in algebraic expression.

Note: While converting the words phrases in the algebraic expression always write carefully used \[t\] for increased word in the question and for decreased word use \[\left( - \right)\] in the algebraic equation and always remember \[3\] times means the number \[3\] is multiplied by any number.
