Evaluate

8 - 2 a

To find the roots of the expression,set the expression equal to 0

8 - 2 a = 0

Move the constant to the right-hand side and change its sign

- 2 a = 0 - 8

Removing 0 doesn't change the value,so remove it from the expression

- 2 a = - 8

Change the signs on both sides of the equation

2 a = 8

Divide both sides

\frac{2 a}{2} = \frac{8}{2}

Divide the numbers

a = \frac{8}{2}
