solve | 3-2x |=8

OpenStudy (anonymous):

2 solutions

OpenStudy (anonymous):

it is -5/2

OpenStudy (anonymous):

x=−5/2,11/2

OpenStudy (jdoe0001):

\(\bf | 3-2x |=8\implies \begin{cases} +(3-2x)=8\\ \quad \\ \bf -(3-2x)=8 \end{cases}\)

OpenStudy (anonymous):

how

OpenStudy (isaiah.feynman):

Gawd!

OpenStudy (jdoe0001):

hmmm there's an assumption you'd know how to simplify a linear equation already, thus the exercise

OpenStudy (anonymous):

The absolute value signs and the minus sign: You can think of them as distance. So the question is: For which x(s) are the distance between 3 and 2x equal to 8.

OpenStudy (anonymous):

When I wrote x(s), I meant that there possibly could be more than one x, not that x is a function of s...

OpenStudy (anonymous):

so how do you solve it

OpenStudy (jdoe0001):

by simplifying the 2 linear equations, and solving for "x"

OpenStudy (anonymous):

Yes, use the two equations which jdoe0001 wrote.
