Solve 0.25x+03/x+3=115

$$\frac { 0.25 x + 03 } { x + 3 } = 115$$

Solve for x

$$x = -\frac{460}{153} = -3\frac{1}{153} \approx -3.006535948$$

Steps for Solving Linear Equation

Variable x cannot be equal to -3 since division by zero is not defined. Multiply both sides of the equation by x+3.

$$0.25x+0\times 3=115\left(x+3\right)$$

Multiply 0 and 3 to get 0.

$$0.25x+0=115\left(x+3\right)$$

Anything plus zero gives itself.

$$0.25x=115\left(x+3\right)$$

Use the distributive property to multiply 115 by x+3.

$$0.25x=115x+345$$

Subtract 115x from both sides.

$$0.25x-115x=345$$

Combine 0.25x and -115x to get -114.75x.

$$-114.75x=345$$

Divide both sides by -114.75.

$$x=\frac{345}{-114.75}$$

Expand \frac{345}{-114.75} by multiplying both numerator and the denominator by 100.

$$x=\frac{34500}{-11475}$$

Reduce the fraction \frac{34500}{-11475} to lowest terms by extracting and canceling out 75.

$$x=-\frac{460}{153}$$
