Q. Solve for c c .\newline31=58c+21 31=\frac{5}{8} c+21 \newlineAnswer: c= c=
  1. Isolate variable term: Isolate the variable term on one side.\newlineTo do this, subtract 2121 from both sides of the equation.\newline31−21=(58)c+21−2131 - 21 = \left(\frac{5}{8}\right)c + 21 - 21\newline$\(10\) = \left(\frac{\(5\)}{\(8\)}\right)c
  2. Solve for c: Solve for c.\(\newline\)To find c, multiply both sides of the equation by the reciprocal of \((5/8)\), which is \((8/5)\).\(\newline\)\(10 \times (8/5) = (5/8)c \times (8/5)\)\(\newline\)\(16 = c\)
