Solve 5.14(-0.7-7)-3.42(14-(-0.7))=

$$5.14(-0.7-7)-3.42(14-(-0.7))=$$

Evaluate

$$-89.852$$

Solution Steps

Subtract 7 from -0.7 to get -7.7.

$$5.14\left(-7.7\right)-3.42\left(14-\left(-0.7\right)\right)$$

Multiply 5.14 and -7.7 to get -39.578.

$$-39.578-3.42\left(14-\left(-0.7\right)\right)$$

The opposite of -0.7 is 0.7.

$$-39.578-3.42\left(14+0.7\right)$$

Add 14 and 0.7 to get 14.7.

$$-39.578-3.42\times 14.7$$

Multiply 3.42 and 14.7 to get 50.274.

$$-39.578-50.274$$

Subtract 50.274 from -39.578 to get -89.852.

$$-89.852$$
