Solve 200*0.22*(-6)+120(-6)+x*0.22*80=0

$$200 \times 0.22 \times ( - 6 ) + 120 ( - 6 ) + x \times 0.22 \times 80 = 0$$

Solve for x

$$x = \frac{615}{11} = 55\frac{10}{11} \approx 55.909090909$$

Steps for Solving Linear Equation

Multiply 200 and 0.22 to get 44.

$$44\left(-6\right)+120\left(-6\right)+x\times 0.22\times 80=0$$

Multiply 44 and -6 to get -264.

$$-264+120\left(-6\right)+x\times 0.22\times 80=0$$

Multiply 120 and -6 to get -720.

$$-264-720+x\times 0.22\times 80=0$$

Subtract 720 from -264 to get -984.

$$-984+x\times 0.22\times 80=0$$

Multiply 0.22 and 80 to get 17.6.

$$-984+x\times 17.6=0$$

Add 984 to both sides. Anything plus zero gives itself.

$$x\times 17.6=984$$

Divide both sides by 17.6.

$$x=\frac{984}{17.6}$$

Expand \frac{984}{17.6} by multiplying both numerator and the denominator by 10.

$$x=\frac{9840}{176}$$

Reduce the fraction \frac{9840}{176} to lowest terms by extracting and canceling out 16.

$$x=\frac{615}{11}$$
