PLEASE I DESPERATELY NEED HELP WITHH THIS!!!!!!! I’ll give brainless and extra points!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Rina8888 [55]

Answer:

1. 4x + 6

2. -15x + 11

5. -x + 4

6. -4x + 7

9. 5x - 2

12. x + 16

Step-by-step explanation:

Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:

x + 3x - 2 + 8

Then, you combine like terms:

4x + 6

That's mostly how you do each one.

PLEASE HELP WITH QUESTIONS 32 and 33 PLEASE
olga2289 [7]

Hey!

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

<h3>Question #32:</h3>

Solve: 4/m - 8 = 8/2

Cross Multiply: 4 * 2 = 8 * (m - 8)

Simplify: 8 = 8m - 64

Flip the Equation: 8m - 64 = 8

Add 64 to both sides: 8m + (-64) + 64 = 8 + 64

Simplify: 8m = 72

Divide both sides by 8: 8m/8 = 72/8

Final Answer: m = 9

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

<h3>Question #33:</h3>

Solve: 7/b + 5 = 10/5

Cross Multiply: 7 * 5 = 10 * (b + 5)

Simplify: 35 = 10b + 50

Flip the Equation: 10b + 50 = 35

Subtract 50 to both sides: 10b + 50 - 50 = 35 - 50

Simplify: 10b = -15

Divide both sides by 10: 10b/10 = -15/10

Final Answer: b = -3/2

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

Find WV 2X+26 2X+31
blsea [12.9K]

Answer:

4

Step-by-step explanation:

Yes u are doing it right

So just find x first

2x + 26 + 2x +31 =13

4x + 57 = 13

4x = - 44

x = - 11

Since now u know x = - 11, and u know

WV =2X+26

So...

2x + 26

=2(-11) + 26

= - 22 + 26

= 4
