solvefor c,cos(x)=2x

solve for

c, cos (x) = 2 x

True for all x; cos (x) = 2 x

Solution steps

cos (x) = 2 x

Both sides are equal

True for all x; cos (x) = 2 x

\frac{2}{7} k - \frac{3}{8} = - \frac{19}{8}

\frac{x}{2} + \frac{x}{6} = 4

\frac{1}{4} c - 3 \frac{1}{2} c + 3 = - \frac{3}{4} c

14 - 12 x + 39 x - 18 x = 239 - 60 x - 6 x

- 18 = - 3 y
