Solution Steps

Subtract 2 from 5 to get 3.

$$6\left(3-1\right)+4\left(5-4-7\right)-5\left(-2\right)$$

Subtract 1 from 3 to get 2.

$$6\times 2+4\left(5-4-7\right)-5\left(-2\right)$$

Multiply 6 and 2 to get 12.

$$12+4\left(5-4-7\right)-5\left(-2\right)$$

Subtract 4 from 5 to get 1.

$$12+4\left(1-7\right)-5\left(-2\right)$$

Subtract 7 from 1 to get -6.

$$12+4\left(-6\right)-5\left(-2\right)$$

Multiply 4 and -6 to get -24.

$$12-24-5\left(-2\right)$$

Subtract 24 from 12 to get -12.

$$-12-5\left(-2\right)$$

Multiply 5 and -2 to get -10.

$$-12-\left(-10\right)$$

The opposite of -10 is 10.

$$-12+10$$

Add -12 and 10 to get -2.

$$-2$$
