Answer:

\huge\boxed{x=\dfrac{1}{3}}

Step-by-step explanation:

\dfrac{1}{x}+\dfrac{1}{3x}=4\\\\\text{Domain:}\ x\neq0\\\\\text{find LCD}=3x\\\\\dfrac{1\cdot3}{x\cdot3}+\dfrac{1}{3x}=4\\\\\dfrac{3}{3x}+\dfrac{1}{3x}=4\\\\\dfrac{3+1}{3x}=4\\\\\dfrac{4}{3x}=\dfrac{4}{1}\qquad\text{cross multiply}\\\\(3x)(4)=(4)(1)\\\\12x=4\qquad\text{divide both sides by 12}\\\\\dfrac{12x}{12}=\dfrac{4}{12}\\\\x=\dfrac{4:4}{12:4}\\\\x=\dfrac{1}{3}\in D

The answers to the questions are:

1. x = 4

2.  x = 1.5

3. x = 1.875

4. x = 1

<h3>2 step equation:</h3>

1. 4x + 3 = 19

4x = 19 - 3

4x = 16

divide by 4

x = 4

<h3>2 step equation w/ fractions:</h3>

(4/3)x + 5 = 17

= 1.33x + 5 = 7

Take like terms

1.33x = 7-5

1.33x = 2

divide through by 1.33x to get 2

x = 2/1.33

x = 1.5

<h3>3. Distributive Property:</h3>

4x(6 - 2) - 10 = 20

Multiply and open the bracket

24x - 8x - 10 = 20

Take like terms

16x = 20+10

16x = 30

x = 30/16

= 1.875

<h3>4. Decimals:</h3>

4.3x + 0.7 = 5

4.3x = 5 - 0.7

4.3x = 4.3

x = 1
