Solve -I(10)+6-1(8)-12=0

$$- I ( 10 ) + 6 - 1 ( 8 ) - 12 = 0$$

Solve for I

$$I = -\frac{7}{5} = -1\frac{2}{5} = -1.4$$

Steps for Solving Linear Equation

Multiply 1 and 8 to get 8.

$$\left(-I\right)\times 10+6-8-12=0$$

Subtract 8 from 6 to get -2.

$$\left(-I\right)\times 10-2-12=0$$

Subtract 12 from -2 to get -14.

$$\left(-I\right)\times 10-14=0$$

Add 14 to both sides. Anything plus zero gives itself.

$$\left(-I\right)\times 10=14$$

Divide both sides by 10.

$$-I=\frac{14}{10}$$

Reduce the fraction \frac{14}{10} to lowest terms by extracting and canceling out 2.

$$-I=\frac{7}{5}$$

Multiply both sides by -1.

$$I=-\frac{7}{5}$$
