Type your math problem... 7-2x

x

Question

Find the roots

x = \frac{7}{2}

Alternative Form

x = 3.5

Evaluate

7 - 2 x

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

7 - 2 x = 0

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

- 2 x = 0 - 7

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

- 2 x = - 7

Change the signs on both sides of the equation

2 x = 7

Divide both sides

\frac{2 x}{2} = \frac{7}{2}

Solution

x = \frac{7}{2}

Alternative Form

x = 3.5
