Solve 3-(-393,5)+2*(-2n1,8)-1*(+185,41)

$$3 - ( - 393,5 ) + 2 \cdot ( - 2 n 1,8 ) - 1 \cdot ( + 185,41 )$$

Evaluate

$$-\frac{16n_{1}}{5}+211,09$$

Solution Steps

The opposite of -393,5 is 393,5.

$$3+393,5+2\left(-2\right)n_{1}\times 0,8-1\times 185,41$$

Add 3 and 393,5 to get 396,5.

$$396,5+2\left(-2\right)n_{1}\times 0,8-1\times 185,41$$

Multiply 2 and -2 to get -4.

$$396,5-4n_{1}\times 0,8-1\times 185,41$$

Multiply -4 and 0,8 to get -3,2.

$$396,5-3,2n_{1}-1\times 185,41$$

Multiply 1 and 185,41 to get 185,41.

$$396,5-3,2n_{1}-185,41$$

Subtract 185,41 from 396,5 to get 211,09.

$$211,09-3,2n_{1}$$

Factor

$$\frac{21109-320n_{1}}{100}$$
