♡ The Question ♡

・3 (x + 4) = x - 8 - 2x

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

* ♡ The Answer ♡

・x = -5

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

・3 (x + 4) = x - 8 - 2x

3 (x + 4) = x - 2x - 8

3 (x + 4) = -x - 8

3 (x + 4): 3x + 12

Apply the distributive law! : a(b + c) = ab + ac

a = 3, b = x, c = 4

= 3x + 3 x 4

Multiply: 3 x 4 = 12

= 3x + 12

3x + 12 = -x - 8

Subtract 12 from both sides!

3x + 12 - 12 = -x - 8 - 12

Simplify!

3x = -x - 20

Add x to both sides!

3x + x = -x - 20 + x

Simplify!

4x/4 = -20/4

Simplify 4x/4 : x

Divide the numbers!

4/4 = 1 = x

Simplify!

-20/4 : -5

-20/4

Apply the fraction rule! : -a/b = -a/b

= -20/4

Divide the numbers!

20/4 = 5

= -5

x = -5

A function f(x) is shown below.

f(x) = x + x + x

Write an equivalent form of f(x) in function notation that contains only one term on the right side of the equation.

Answers

Answer:

f(x) = 3x

Step-by-step explanation:

when adding x (the same variable) to eachother when there is nothing in front, you always assume the coefficient is 1. since there are 3 x's, (1)x+(1)x+(1)x=3x. hope this helps:)

It would be 0 because 0=3x and 3x=0 so the answer would be x=0
