Solve 400-4*10^5/3x=0

$$400- \frac{ 4 \times { 10 }^{ 5 } }{ 3 } x=0$$

Solve for x

$$x=\frac{3}{1000}=0.003$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 3.

$$1200-4\times 10^{5}x=0$$

Calculate 10 to the power of 5 and get 100000.

$$1200-4\times 100000x=0$$

Multiply 4 and 100000 to get 400000.

$$1200-400000x=0$$

Subtract 1200 from both sides. Anything subtracted from zero gives its negation.

$$-400000x=-1200$$

Divide both sides by -400000.

$$x=\frac{-1200}{-400000}$$

Reduce the fraction \frac{-1200}{-400000} to lowest terms by extracting and canceling out -400.

$$x=\frac{3}{1000}$$
