The value of c that makes the equation true is: c = -13/21.
An equation is a mathematical statement whose values on the right and left sides are equal.
Given:
c + 15 = 23c + 2 − 43c
Find the value of c
c + 15 = -20c + 2
c + 20c = -15 + 2
21c = -13
c = -13/21
Thus, the value of c that makes the equation true is: c = -13/21.

The value of c which makes the equation c + 15 = 23c + 2 − 43c true is –13/21
c + 15 = 23c + 2 − 43c
The value of c in the expression above can be obtained as illustrated below:
c + 15 = 23c + 2 − 43c
Collect like terms
c – 23c + 43c = 2 − 15
21c = –13
Divide both side by 21
c = –13/21
Thus, from the calculation made above, we can conclude that the value of c which makes the equation true is –13/21
