Simplifying

7x + -4y = 23


Solving

7x + -4y = 23


Solving for variable 'x'.


Move all terms containing x to the left, all other terms to the right.


Add '4y' to each side of the equation.

7x + -4y + 4y = 23 + 4y


Combine like terms: -4y + 4y = 0

7x + 0 = 23 + 4y

7x = 23 + 4y


Divide each side by '7'.

x = 3.285714286 + 0.5714285714y


Simplifying

x = 3.285714286 + 0.5714285714y

blagie [28]
To solve this, first we'll find the area of the rectangle A,

Area=length × width
?=24m×20m
480m=24m×20m
480m squared=area of the rectangle A

now we'll find the width of rectangle B,
"the width of rectangle B is 12 meters less than the width of rectangle A",
20m-12m= 8m
8m=width of rectangle B

finally we'll find the length of rectangle B,
area of the rectangle B= 480msquared
width= 8m
length=? (to find this divide the area by the width)
480÷8=60m
length of the rectangle B=60m

mash [69]

Answer:

1. Infinitely Many Solutions

2. Zero Solutions

3. One Solution ( x = 6 )

Step-by-step explanation:

1.

12x + 8 = 2( 6x + 4 )

12x + 8 = 12x + 8

2.

2( 2x + 1 ) = 4x + 3

4x + 2 = 4x + 3

2 = 3

3.

4( x + 1 ) = 3x + 10

4x + 4 = 3x + 10

x + 4 = 10

x = 6

Hopefully this helps!
