Solve 7.5-8.66*6+5*4-20-x*6=0

$$7.5-8.66 \cdot 6+5 \cdot 4-20-x \times 6 = 0$$

Solve for x

$$x=-7.41$$

Steps for Solving Linear Equation

Multiply 8.66 and 6 to get 51.96.

$$7.5-51.96+5\times 4-20-x\times 6=0$$

Subtract 51.96 from 7.5 to get -44.46.

$$-44.46+5\times 4-20-x\times 6=0$$

Multiply 5 and 4 to get 20.

$$-44.46+20-20-x\times 6=0$$

Add -44.46 and 20 to get -24.46.

$$-24.46-20-x\times 6=0$$

Subtract 20 from -24.46 to get -44.46.

$$-44.46-x\times 6=0$$

Multiply -1 and 6 to get -6.

$$-44.46-6x=0$$

Add 44.46 to both sides. Anything plus zero gives itself.

$$-6x=44.46$$

Divide both sides by -6.

$$x=\frac{44.46}{-6}$$

Expand \frac{44.46}{-6} by multiplying both numerator and the denominator by 100.

$$x=\frac{4446}{-600}$$

Reduce the fraction \frac{4446}{-600} to lowest terms by extracting and canceling out 6.

$$x=-\frac{741}{100}$$
