Answer:

x = 2

y = -1

Step-by-step explanation:

Since it gives you the value of y already, just plug that into the equation, like so:

y = 4x - 9

x - 3 = 4x - 9

<em><u>Subtract the x from both sides:</u></em>

x - 3 = 4x - 9

-x       - x

__________

-3 = 3x - 9

<em><u>Then, add 9 to both sides:</u></em>

-3 = 3x - 9

+9        + 9

________

6 = 3x

<em><u>Divide both sides by 3:</u></em>

2 = x

<em><u>Now plug in x for y:</u></em>

y = x - 3

y = 2 - 3

y = -1

I’m confused on this one
Mashutka [201]

Greetings!

The formula for the area of any triangle is as followed:

A_{triangle}=\frac{bh}{2}

-------------------------------------------------------------------------------------------------------------

<u>Let Statements:</u>

Let the variable...

→ b represent the length of the base of the triangle

→ h represent the length of the height of the triangle

-------------------------------------------------------------------------------------------------------------

Using the information provided from the question, we can substitute its values in place of the variables and solve for the last remaining variable:

10=\frac{(4)(x+3)}{2}

Distribute the parenthesis<em> (The Distributive Property) </em>:

10=\frac{((4)(x)+(4)(3))}{2}

10=\frac{4x+12}{2}

Reduce the fraction to lowest terms:

10=2x+6

Add -6 to both sides of the equation:

(10)+(-6)=(2x+6)+(-6)

4=2x

Divide both sides of the equation by 2:

\frac{4}{2}=\frac{2x}{2}

2=x

-------------------------------------------------------------------------------------------------------------

The Answer to this Problem is:

\boxed{x=2}

-------------------------------------------------------------------------------------------------------------

I hope this helped!
