c - 7 = -9

Answer 1

• IN THIS EQUATION WE HAVE TO FIND "C"
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE SO WHEN IT WILL GO THAT SIDE AFTER -9
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE SO WHEN IT WILL GO THAT SIDE AFTER -9 THEN IT -7 WILL BE +7
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE SO WHEN IT WILL GO THAT SIDE AFTER -9 THEN IT -7 WILL BE +7 C- 7 = - 9
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE SO WHEN IT WILL GO THAT SIDE AFTER -9 THEN IT -7 WILL BE +7 C- 7 = - 9 C = - 9 + 7
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE SO WHEN IT WILL GO THAT SIDE AFTER -9 THEN IT -7 WILL BE +7 C- 7 = - 9 C = - 9 + 7 C = - 16
• IN THIS EQUATION WE HAVE TO FIND "C" FIRST OF ALL WE WILL WRITE THE EQUATION AGAIN C - 7 = - 9 NOW 7 IS NEGATIVE SO WHEN IT WILL GO THAT SIDE AFTER -9 THEN IT -7 WILL BE +7 C- 7 = - 9 C = - 9 + 7 C = - 16 BECAUSE NEGATIVE SIGN GOES TO BIGGER NO. IT WILL BE - 16

Answer 2

`c = 2`

Explanation:

In order to find the answer to this question you must add 7 on both sides.

`c-7=-9`

`+ 7 + 7`

`-9 + 7 = -2`

`c = -2`

Hope this helps.
