Solve {l}{-2,7*(-1,2)+3,5*(-2,8)}{-7,4*0,6-3,8*(-2,3)}

$$\left. \begin{array} { l } { - 2,7 \cdot ( - 1,2 ) + 3,5 \cdot ( - 2,8 ) } \\ { - 7,4 \cdot 0,6 - 3,8 \cdot ( - 2,3 ) } \end{array} \right.$$

Evaluate

$$-2,26$$

Solution Steps

Multiply -2,7 and -1,2 to get 3,24.

$$3,24+3,5\left(-2,8\right)-7,4\times 0,6-3,8\left(-2,3\right)$$

Multiply 3,5 and -2,8 to get -9,8.

$$3,24-9,8-7,4\times 0,6-3,8\left(-2,3\right)$$

Subtract 9,8 from 3,24 to get -6,56.

$$-6,56-7,4\times 0,6-3,8\left(-2,3\right)$$

Multiply 7,4 and 0,6 to get 4,44.

$$-6,56-4,44-3,8\left(-2,3\right)$$

Subtract 4,44 from -6,56 to get -11.

$$-11-3,8\left(-2,3\right)$$

Multiply 3,8 and -2,3 to get -8,74.

$$-11-\left(-8,74\right)$$

The opposite of -8,74 is 8,74.

$$-11+8,74$$

Add -11 and 8,74 to get -2,26.

$$-2,26$$

Factor

$$-2,26$$
