First of all we need to convert fractions into decimals or decimals into fractions:
6.4 - y = 6 2/5 6.4 - y = 6.4 / - 6.4 (both sides) -y = 0 / * (-1) (both sides) y = 0
6.4 − y = 6 5 2 − y = 6 5 2 − 6.4 − y = 6 10 4 − 6.4 − y = 0 y = 0
To solve the equation 6.4 − y = 6 5 2 , we simplify the right side to 6.4 . By rearranging the equation, we find that y = 0 .
