Answer 1

Answer:

x = 12

Step-by-step explanation:

(10x - 20)° + (6x + 8)°= 180°

(Linear pair angles)

(10x - 20 + 6x + 8)°= 180°

(16x - 12)°= 180°

16x - 12 = 180

16x = 180 + 12

16x = 192

x = 192/16

x = 12

Answer 2

Answer:

so x would equal 12

Step-by-step explanation:

(10x - 20)° + (6x + 8)°= 180°

so you are going to want to combine like terms which would be

10x and 6x, and 20,8

10x+6x=16x

20-8=12

16x-12=180

now you want to get 12 on the opposite side of the equal side so you add (since it is negative) 12 to each side

which gets rid of the first 12

16x=180+12

now you can add 180+12

and you get 192

so now we want to get x by itself in order to do that you must divide

you are going to divide by 16 an each side and the 16 cancels out the first 16

16x/16=192/16

x=192/16

and 192 divided by 16 is 12

so you answer is

x=12

Hope this made sense :)

Need help with this question

Answers

Answer:

C. x = 3

Step-by-step explanation:

8x - 8 = 2x + 10

get the x on it's own

8x - 8 + 8 = 8x

2x + 10 + 8 = 2x + 18

8x = 2x + 18

8x - 2x = 6x

2x + 18 - 2x = 18

6x = 18

now divide each side by 6

6x / 6 = x

18 / 6 = 3

x = 3

X=3

Explanation

8x-8=2x+10

6x=18

x=3

7x-3= -24 what is x and how do you find it?

Answers

Answer:

x = -3

Step-by-step explanation:

7x - 3 = -24 (Given)

7x - 3 + 3 = -24 + 3 (Added 3 on both sides by using the addition property of equality)

7x = -21 (Simplified)

7x/7 = -21/7 (Divided 7 on both sides by using the division property of equality)

x = -3 (Simplified)

Therefore, x = -3.

Answer:

x= -3

Step-by-step explanation:

You do the opposite.

So,

-24 +3

= -21

-21/ 7

= -3

Therefore, the answer is -3
