Solve for C. <br>4/ 7(B - C) = A <br><br>C = ___
klio [65]

Answer:

C = ¼(4B – 7A)

Step-by-step explanation:

⁴/₇(B – C) = A                Multiply each side by 7

  4(B - C) = 7A               Remove parentheses

 4B – 4C = 7A              Subtract 4B from each side

        -4C = 7A – 4B      Multiply each side by -1

         4C = -7A + 4B     Divide each side by 4

          C = ¼(4B – 7A)
