(x/2)=x

Solution

(\frac{x}{2}) = x

x = 0

Solution steps

(\frac{x}{2}) = x

Expand

(\frac{x}{2}) : \frac{x}{2}

\frac{x}{2} = x

Multiply both sides by

2

x = 2 x

Move

2 x

to the left side

- x = 0

Divide both sides by

- 1

x = 0

c, x - cos (x) = 0

2 x - \frac{2}{3} = \frac{3}{4} - x

\frac{2 x - 6}{2} + 3 = 10

\frac{5}{6} = \frac{15}{18}

\frac{3 x}{5} - 0.5 = 1.9
