Answer:

<em>2</em><em>x</em><em>^</em><em>2</em><em> </em><em>+</em><em> </em><em>3</em><em>x</em><em> </em><em>-</em><em> </em><em>2</em>

Step-by-step explanation:

=> <em> </em><em>area</em><em> of</em><em> </em><em>rectangle</em><em> </em><em>=</em><em> </em><em>length</em><em>*</em><em>width</em>

<em> </em><em> </em><em>=</em><em>></em><em> </em><em>length</em><em> </em><em>=</em><em> </em><em>(</em><em>2</em><em>x</em><em> </em><em>-</em><em>1</em><em>)</em>

<em>=</em><em>></em><em> </em><em>width</em><em> </em><em>=</em><em> </em><em>(</em><em>x </em><em>+</em><em> </em><em>2</em><em>)</em>

<em>=</em><em>></em><em> </em><em>area </em><em>=</em><em> </em><em>(</em><em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>1</em><em>)</em><em> </em><em>(</em><em>x </em><em>+</em><em> </em><em>2</em><em>)</em>

<em>=</em><em>></em><em> </em><em>area=</em><em> </em><em> </em><em>2</em><em>x</em><em>(</em><em>x </em><em>+</em><em> </em><em>2</em><em>)</em><em> </em><em>-</em><em> </em><em>1</em><em>(</em><em>x </em><em>+</em><em> </em><em>2</em><em>)</em>

<em>=</em><em>></em><em> </em><em>area</em><em> </em><em>=</em><em> </em><em>2</em><em>x</em><em>^</em><em>2</em><em> </em><em>+</em><em> </em><em>4</em><em>x</em><em> </em><em>-</em><em> </em><em>1</em><em>x</em><em> </em><em>-</em><em> </em><em>2</em>

<em>=</em><em>></em><em> </em><em>area </em><em>=</em><em> </em><em>2</em><em>x</em><em>^</em><em>2</em><em> </em><em>+</em><em> </em><em>3</em><em>x</em><em> </em><em>-</em><em> </em><em>2</em>

Explain your answer !! <br> Have a nice day <br><br> Will give braisnlt
Viktor [21]

Answer:

(3,-4) or x=3 and y= -4

Step-by-step explanation:

I'm going to solve this by substitution

We first need to get a variable by itself in one of the two equations (it doesn't matter which variable and the equation you do the work on doesn't matter either)

I'm going to solve for y in the second equation

-4x-4y=4

add 4y and subtract 4 from both sides to get

-4x-4=4y

Divide by 4 to get

-x-1=y

We can plug this value in for y into the first equation and get

4x+5(-x-1)= -8

Solve for x

4x-5x-5= -8

-x-5= -8

-x= -3

x=3

We can plug this value into one of the first two equations and solve for y

4(3)+5y= -8

12+5y= -8

5y= -20

y= -4

Therefore the solution is (3,-4) or x=3 and y= -4
