Question

Help me solve plz 3=-2|1/4s-5|+3

Answer 1

We want to solve the equation:


`3=-2| (1)/(4)s-5 |+3`



First, subtract 3 from both sides:


`0=-2| (1)/(4)s-5|`


Clearly,
`| (1)/(4)s-5|` must be equal to 0, which means
`(1)/(4)s-5` must be equal to 0, so we solve:



`(1)/(4)s-5=0\\\\(1)/(4)s=5\\\\s=5\cdot4=20`


Answer: s=20
