Solve -2*0.1*3*t+10*3-80*0.1-5=0

$$- 2 \times 0.1 \times 3 \times t + 10 \times 3 - 80 \times 0.1 - 5 = 0$$

Solve for t

$$t = \frac{85}{3} = 28\frac{1}{3} \approx 28.333333333$$

Steps for Solving Linear Equation

Multiply -2 and 0.1 to get -0.2.

$$-0.2\times 3t+10\times 3-80\times 0.1-5=0$$

Multiply -0.2 and 3 to get -0.6.

$$-0.6t+10\times 3-80\times 0.1-5=0$$

Multiply 10 and 3 to get 30.

$$-0.6t+30-80\times 0.1-5=0$$

Multiply 80 and 0.1 to get 8.

$$-0.6t+30-8-5=0$$

Subtract 8 from 30 to get 22.

$$-0.6t+22-5=0$$

Subtract 5 from 22 to get 17.

$$-0.6t+17=0$$

Subtract 17 from both sides. Anything subtracted from zero gives its negation.

$$-0.6t=-17$$

Divide both sides by -0.6.

$$t=\frac{-17}{-0.6}$$

Expand \frac{-17}{-0.6} by multiplying both numerator and the denominator by 10.

$$t=\frac{-170}{-6}$$

Reduce the fraction \frac{-170}{-6} to lowest terms by extracting and canceling out -2.

$$t=\frac{85}{3}$$
