Basic Math Examples

$0.4 z + 0.5 (20) = 0.2 (114)$

Step 1

Multiply

$0.5$ by

$20$ .

$0.4 z + 10 = 0.2 (114)$

Step 2

Multiply

$0.2$ by

$114$ .

$0.4 z + 10 = 22.8$

Step 3.1

Subtract

$10$ from both sides of the equation.

$0.4 z = 22.8 - 10$

Step 3.2

Subtract

$10$ from

$22.8$ .

$0.4 z = 12.8$

$0.4 z = 12.8$
