Question

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

Answer 1

We want to solve the equation:

$3=-2| \frac{1}{4}s-5 |+3$



First, subtract 3 from both sides:

$0=-2| \frac{1}{4}s-5|$


Clearly, $| \frac{1}{4}s-5|$ must be equal to 0, which means $\frac{1}{4}s-5$ must be equal to 0, so we solve:


$\frac{1}{4}s-5=0\\\\\frac{1}{4}s=5\\\\s=5\cdot4=20$


Answer: s=20
