Solve 4-2n - ScanMath

Evaluate

4 - 2 n

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

4 - 2 n = 0

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

- 2 n = 0 - 4

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

- 2 n = - 4

Change the signs on both sides of the equation

2 n = 4

Divide both sides

\frac{2 n}{2} = \frac{4}{2}

Divide the numbers

n = \frac{4}{2}
