Answer:

c = 15

Step-by-step explanation:

The angles are4 a linear pair and are supplementary, so the sum of their measures is 180 deg.

7c - 7 + 6c - 8 = 180

13c - 15 = 180

13c = 195

c = 15

The answer should be 15.

Explanation:
The line equates to 180, so you would put both equations (7c-7 , 6c-8) together and equal it to 180°.
So, it would come out looking like this:
7c-7+6c-8=180.

You’d add 7c and 6c to get 13c, and then subtract -8 from -7 (-7-8) to get -15.
The equation would now look like this.
13c-15= 180.

You’d add 15 to 180 to get 195. Then, you’d divide 195 by 13 to get 15, which would mean c=15.

Answer:

<h2><u><em>no solution, the equation is false</em></u></h2>

Step-by-step explanation:

what is the solution for the following equation 3(2x+3)=2(3x+4)?

3 * (2x + 3) = 2 * (3x + 4)

6x + 9 = 6x + 8

6x - 6x = -9  + 8
