**Please let me know which one you solved along with the answer**

Answers

Answer:

Pic 1: [tex]x=31[/tex]

Pic 2: [tex]x=20[/tex]

Step-by-step explanation:

Picture 1:

[tex]2x+x-3=90\\3x-3=90\\3x=93\\x=31[/tex]

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

Picture 2:

[tex]7x+x+20=180\\8x+20=180\\8x=160\\x=20[/tex]

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.

Step-by-step explanation:

First picture

We can make an equation with this

2x+x-3=90

3x=93

x=31 degrees

Second picture

We can make and equation

7x+x+20=180

8x=160

x= 20

-4p = -28

/-4        /-4

p = 7

3. -3 1/2 = -1 1/4b

   /1.25      /1.25

-2 4/5 = -b

2 4/5 = b

or

2.8 = b

Answer:

Step-by-step explanation:

Question 1:

-7 = w + 5

- 5        - 5

-12 = w      

w = -12

Question 2:

-4p + 38 = 10

      - 38   - 38

-4p = -28

-----    -----       fraction bar... -4p divided by -4, -28 divided by -4
