Solve 0.3x+0.06left(3100-xright)=123.00

$$0.3x+0.06 \left( 3100-x \right) =123.00$$

Solve for x

$$x=-262.5$$

Steps for Solving Linear Equation

Use the distributive property to multiply 0.06 by 3100-x.

$$0.3x+186-0.06x=123$$

Combine 0.3x and -0.06x to get 0.24x.

$$0.24x+186=123$$

Subtract 186 from both sides.

$$0.24x=123-186$$

Subtract 186 from 123 to get -63.

$$0.24x=-63$$

Divide both sides by 0.24.

$$x=\frac{-63}{0.24}$$

Expand \frac{-63}{0.24} by multiplying both numerator and the denominator by 100.

$$x=\frac{-6300}{24}$$

Reduce the fraction \frac{-6300}{24} to lowest terms by extracting and canceling out 12.

$$x=-\frac{525}{2}$$
