6 + 5c = -29
•You are trying to find C
Therefore you make C your subject by subtracting 6 on both sides then divide by 5.
Like this ;
6 - 6 + 5c = -29 - 6
5c/5 = -35/5
c = -7
hence
C = -7.
To check or prove that your answer is correct, simply sustitute (-7) into the equation in place of C and if the result is -29 than its the correct answer.
•Check;
6 + 5 (-7) = ?
6 + (-35) = ?
6 - 35 = -29
Your answer is proved so C = -7
