Please make it more specific as to what the fraction is next time. The LaTeX way to write a fraction is \frac{numerator}{denominator}

So, your equation is: $$\frac{2}{5}x+ 4 = 10$$

Isolate x and its coefficient by subtracting 4: $$\frac{2}{5}x=6$$

Divide each side of the equation by  $$\frac{2}{5}$$(The coefficient of x) [or multiply by the reciprocal of the coefficient of x]:

$$x = \frac{6}{\frac{2}{5}} = \frac{6*5}{2} = \frac{30}{2} = 15$$

x = 15
