solvefor c,f=7c-c/d

solve for

c, f = 7 c - \frac{c}{d}

c = \frac{fd}{7 d - 1}; d \neq = 0, d \neq = \frac{1}{7}

Solution steps

f = 7 c - \frac{c}{d}

Switch sides

7 c - \frac{c}{d} = f

Multiply both sides by

d

7 c d - c = fd; d \neq = 0

Factor

7 c d - c : c (7 d - 1)

c (7 d - 1) = fd; d \neq = 0

Divide both sides by

7 d - 1; d \neq = 0, d \neq = \frac{1}{7}

c = \frac{fd}{7 d - 1}; d \neq = 0, d \neq = \frac{1}{7}

x, x - 4 y = - 6

6 k - 17 = 37

y = \frac{1}{2} 0

2 y - 3 = 7

x + 3 (x - 5) = x - 2 (x + 5)
