How do you solve an equation in one variable

Is this what you mean? 3x+4x+6=13
Ok if this is it then you combine like terms.
In this case our like terms are 3x and 4x.
That will give us:
7x+6=13
Now subtract 6 from each side.
7x= 7
Divide each side by 7
X= 1

<h2>Intersection and Union of Sets</h2><h3>Answer:</h3>

$A \cup B = \{ a, b, c, d, e \}$

$B \cap C = \{ d, e \}$

$A \cup C = \{ a, b, c, d, e, f \}$

<h3>Step-by-step explanation:</h3>

Given:

$A = \{ a, b, c, d \}$

$B = \{ b, d, e \}$

$C = \{ d, e, f \}$

The Union ( $\cup$ ) of sets $A$ and $B$ is just a set containing all the elements of sets $A$ and $B$ . However, elements that are present in both sets should not repeat in the Union of Sets as the elements of a set should distinct be from each other.

Part i:

$A \cup B \\ \{ a, b, c, d \} \cup \{ b, d, e \} \\ \{ a, b, c, d, e \}$

The Intersection ( $\cap$ ) of sets $A$ and $B$ is just a set containing all the elements that are both present in sets $A$ and $B$ .

Part ii:

$B \cap C \\ \{ b, d, e \} \cap \{ d, e, f \} \\ \{ d, e \}$

Part iii:

$A \cup C \\ \{ a, b, c, d, \} \cup \{d, e, f \} \\ \{ a, b, c, d, e, f \}$

Answer:

Graph attached
Slope is 7

Step-by-step explanation:

First plot the two points on the graph (0, 0) and (1/3, 7/3)

Then connect those points by a line and extend the line

<em>See attached</em>

<u>Slope is:</u>

m = 7/3 : 1/3 = 7/3*3 = 7
