Q:

what is the solution to the equation |10-5y| =20 a) y=2b) y=4c) y=6d) y=10

Accepted Solution

A:
Answer:The correct answer is option c) y = 6Step-by-step explanation:It is given that|10-5y| =20 Check each optiona) y = 2|10 - 5y| = |10 - 5 * 2| = | 10 - 10 | = 0 β‰  20b) y = 4|10 - 5y| = |10 - 5 * 4| = | 10 - 20 | = |-10| = 10 β‰  20c) y = 6|10 - 5y| = |10 - 5 * 6| = | 10 - 30 | = |-20| = 20d) y = 10|10 - 5y| = |10 - 5 * 10| = | 10 - 50 | = |-40| Β β‰  20From the above result we get the correct answer is option c) y = 6
