Algebraic expression ; 3x = 39

Step-by-step explanation:

Let the unknown number be x

$3\times x = 39\\\\3x = 39$

Further solving

$\mathrm{Divide\:both\:sides\:by\:}3\\\\\frac{3x}{3}=\frac{39}{3}\\\\Simplify\\\\x =13$

Answer 2

Answer:

13

Step-by-step explanation:

the product of 3 and a number

that means 3*something

we can call something "x"

so we have

3*x = 3x

is 39

That means that something is equal to 39

let me write it

something = 39

but we know that this something is 3x

so we have

$3x=39\\\\\frac{1}{3}*3x=\frac{1}{3}*39\\\\x=\frac{39}{3} \\\\x=\frac{3*13}{3} \\\\x=13$

so the number is 13
