Question

Find the roots

a = \frac{7}{2}

Alternative Form

a = 3.5

Evaluate

7 - 2 a

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

7 - 2 a = 0

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

- 2 a = 0 - 7

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

- 2 a = - 7

Change the signs on both sides of the equation

2 a = 7

Divide both sides

\frac{2 a}{2} = \frac{7}{2}

Solution

a = \frac{7}{2}

Alternative Form

a = 3.5
