number added to the difference between triple the number and thirteen Translate into a variable expression. (Use x for your variable. Do not simplify.)

Step-by-step explanation:

Given

Represent the number with x

Required

Translate the statements to expression

First, we need to get triple of x:

Next is to get the difference between 3x and 13

This is represented as

Lastly, Add x to the above:

Hence, the variable expression is 4x - 13

3( -2x + 4)

let's equal the given soln to 0

3(-2x+4) = 0

-6x + 12 = 0

-6x + 12 - 12 = 0-12

-6x = -12

we divide both sides by -6

-6x/-6 = -12/-6

x = 2
