Solve 27+0.2x+21+5-9-12-7=x

$$27 + 0.2 x + 21 + 5 - 9 - 12 - 7 = x$$

Solve for x

$$x=31.25$$

Steps for Solving Linear Equation

Add 27 and 21 to get 48.

$$48+0.2x+5-9-12-7=x$$

Add 48 and 5 to get 53.

$$53+0.2x-9-12-7=x$$

Subtract 9 from 53 to get 44.

$$44+0.2x-12-7=x$$

Subtract 12 from 44 to get 32.

$$32+0.2x-7=x$$

Subtract 7 from 32 to get 25.

$$25+0.2x=x$$

Subtract x from both sides.

$$25+0.2x-x=0$$

Combine 0.2x and -x to get -0.8x.

$$25-0.8x=0$$

Subtract 25 from both sides. Anything subtracted from zero gives its negation.

$$-0.8x=-25$$

Divide both sides by -0.8.

$$x=\frac{-25}{-0.8}$$

Expand \frac{-25}{-0.8} by multiplying both numerator and the denominator by 10.

$$x=\frac{-250}{-8}$$

Reduce the fraction \frac{-250}{-8} to lowest terms by extracting and canceling out -2.

$$x=\frac{125}{4}$$
