Solve (x-0.3x-0.13x)*0.87=100

$$(x-0.3x-0.13x) \times 0.87=100$$

Solve for x

$$x = \frac{1000000}{4959} = 201\frac{3241}{4959} \approx 201.653559185$$

Steps for Solving Linear Equation

Divide both sides by 0.87.

$$x-0.3x-0.13x=\frac{100}{0.87}$$

Expand \frac{100}{0.87} by multiplying both numerator and the denominator by 100.

$$x-0.3x-0.13x=\frac{10000}{87}$$

Combine x and -0.3x to get 0.7x.

$$0.7x-0.13x=\frac{10000}{87}$$

Combine 0.7x and -0.13x to get 0.57x.

$$0.57x=\frac{10000}{87}$$

Divide both sides by 0.57.

$$x=\frac{\frac{10000}{87}}{0.57}$$

Express \frac{\frac{10000}{87}}{0.57} as a single fraction.

$$x=\frac{10000}{87\times 0.57}$$

Multiply 87 and 0.57 to get 49.59.

$$x=\frac{10000}{49.59}$$

Expand \frac{10000}{49.59} by multiplying both numerator and the denominator by 100.

$$x=\frac{1000000}{4959}$$
