0.5 t + 0.25 (t + 16) = 4 + 0.75 t

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere are

2

digits to the right of the decimal point, therefore multiply by

100

0.5 t \cdot 100 + 0.25 (t + 16) \cdot 100 = 4 \cdot 100 + 0.75 t \cdot 100

Simplificar

50 t + 25 (t + 16) = 400 + 75 t

Expandir

25 (t + 16) : 25 t + 400

50 t + 25 t + 400 = 400 + 75 t
