Answer:

x = - 8

Step-by-step explanation:

To solve for x, isolate it by "moving" everything else over to the other side. This is done in reverse BEDMAS order using the reverse operations of number you want to move.

3 (2x-1 ) +7 = - 44 Simplify first using distributive property over the brackets

6x - 3 + 7 = - 44 Combine like terms, terms that have the same variables

6x + 4 = - 44

6x + 4 - 4 = - 44 - 4 Subtract 4 from both sides to cancel it out on the left side

6x = - 48

6x/6 = - 48/6 Divide by sides by 6 to cancel out the 6 from 6x

x = - 8 Final answer

Solve for x, −2 (4x+4) −3x − 2 = 34 help needed, thanks!

Arada [10]

Hey there!

The answer to your question is $-2 \frac{3}{11}$

$-2(4x+4) - 3x -2= 34$ Write the equation

$-8x - 8 - 3x - 2 = 34$ Distribute -2

$-11x-10 = 34$ Combine like terms

$-11x = 24$ Add 10 to both sides

$-2 \frac{3}{11}$ Divide both sides by -11

Hope it helps and have a great day!

Use the algebraic expressions for the length and width of Marlene's living room found in the

krok68 [10]

Answer:

<em>The area of Marlien's living room is 420 square ft</em>

Step-by-step explanation:

Before calculating the real dimensions of Marlien's living room, we must find the value of x.

Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.

The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:

$2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2$

Simplifying:

-10 + x - 2 = 2

x = 10 + 2 + 2

x = 14

Since x=14 feet, the dimensions of Marlien's living room are

width=x=14 feet

length=2x+2=30 feet

Thus the area is:

A = 14*30 = 420 square ft

The area of Marlien's living room is 420 square ft
