Solve 16000000/x/4-1=7

$$\frac{ \frac{ 16000000 }{ x } }{ 4 } -1 = 7$$

Solve for x

$$x=500000$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 4.

$$\frac{16000000}{x}-4=28$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 4 times \frac{x}{x}.

$$\frac{16000000}{x}-\frac{4x}{x}=28$$

Since \frac{16000000}{x} and \frac{4x}{x} have the same denominator, subtract them by subtracting their numerators.

$$\frac{16000000-4x}{x}=28$$

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.

$$16000000-4x=28x$$

Subtract 28x from both sides.

$$16000000-4x-28x=0$$

Combine -4x and -28x to get -32x.

$$16000000-32x=0$$

Subtract 16000000 from both sides. Anything subtracted from zero gives its negation.

$$-32x=-16000000$$

Divide both sides by -32.

$$x=\frac{-16000000}{-32}$$

Divide -16000000 by -32 to get 500000.

$$x=500000$$
