Solve 1-1a/2-2a - ScanMath

Evaluate

1 - (1 \times \frac{a}{2}) - 2 a

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

1 - (1 \times \frac{a}{2}) - 2 a = 0

Calculate

1 - \frac{a}{2} - 2 a = 0

Subtract the terms

More Steps

\frac{2 - a}{2} - 2 a = 0

Subtract the terms

More Steps

\frac{2 - 5 a}{2} = 0

Simplify

2 - 5 a = 0

Move the constant to the right side

- 5 a = 0 - 2

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

- 5 a = - 2

Change the signs on both sides of the equation

5 a = 2

Divide both sides

\frac{5 a}{5} = \frac{2}{5}

Solution

a = \frac{2}{5}

Alternative Form

a = 0.4
