Solve I=-0,8-0,2/0,2*0,8*1,6+0,5*0,940

$$I = \frac { - 0,8 - 0,2 } { 0,2 \cdot 0,8 \cdot 1,6 + 0,5 \cdot 0,940 }$$

Solve for I

$$I=-\frac{500}{363}\approx -1,377410468$$

Steps for Solving Linear Equation

Subtract 0,2 from -0,8 to get -1.

$$I=\frac{-1}{0,2\times 0,8\times 1,6+0,5\times 0,94}$$

Multiply 0,2 and 0,8 to get 0,16.

$$I=\frac{-1}{0,16\times 1,6+0,5\times 0,94}$$

Multiply 0,16 and 1,6 to get 0,256.

$$I=\frac{-1}{0,256+0,5\times 0,94}$$

Multiply 0,5 and 0,94 to get 0,47.

$$I=\frac{-1}{0,256+0,47}$$

Add 0,256 and 0,47 to get 0,726.

$$I=\frac{-1}{0,726}$$

Expand \frac{-1}{0,726} by multiplying both numerator and the denominator by 1000.

$$I=\frac{-1000}{726}$$

Reduce the fraction \frac{-1000}{726} to lowest terms by extracting and canceling out 2.

$$I=-\frac{500}{363}$$

Assign I

$$I≔-\frac{500}{363}$$
