baherus [9]3 years ago

Answer:

x= 6

Step-by-step explanation:

3(x-4)-x+7= (4x+9)+(x-32)

Distribute 3 through the parenthesis.

3x-12-x+7=4x+9+(x-32)

When there is a "+" in front of the parenthesis the expression remains the same.

3x-12-x+7= 4x+9+x-32

Collect the like terms.

2x-12+7= 4x+9+x-32

Calculate the sum.

2x-5=4x+9+x-32

Collect the like terms.

2x-5= 5x+9-32

Calculate the difference.

2x-5= 5x-23

Move the variable to the left side and change the sign.

2x-5x+5= -23

Move the constant to the right side and change its sign.

2x-5x= -23+5

Collect the like terms.

-3x=-18

Divide both sides of the equation by -3.

<u>-3x</u>= <u>-18</u>

-3     -3

Solution:

x= 6

The length of a rectangle is 2 feet more than 5 its width. The perimeter is 52 feet. Find the dimension of the rectangle
Ber [7]

Answer: The length is 22 feet. The width is 4 feet.

Step-by-step explanation: Create an equation for the length: 2+5w=52.

Now combine the two sides to get 4+10w=52. Plug in some numbers that seem reasonable. I started with 4, checked my work and found that it was right. This problem is all about trial and error.

So, 4+10(4)= 44. Make sure to remember the width, so add 4 for each side: 44+8. 44+8=52. Hope this helps :)
