Question

Solve |2x + 1 / 3| = 4

X= 2 or X = 5
X = 11/2 or -13 / 2
X = -11/2 or -13/2
X= -11/2 or 13/2

Answer 1

is this \[|2x+\frac{1}{3}|==4\] or
\[|\frac{2x+1}{3}|=4\]?

Answer 2

The second one @satellite73

Answer 3

multiply both sides by 3 first to get rid of the fraction
leave the absolute value sign there
what do you get?

Answer 4

@sateillte73 I got 7 and 12

Answer 5

i get \[|2x+1|=12\]

Answer 6

then solve two equations \[2x+1=12\] and \[2x+1=-12\]

Answer 7

@sateillte73 I got 11 and -13

Answer 8

you get \[2x=11\] or \[2x=-13\] you still have to solve for \(x\)

Answer 9

What would I plug in for X ? Can I even solve for x ?

Answer 10

@sateillte73

Answer 11

You divide both sides by 2 for each one

Answer 12

Okay that's what I thought @Kdr1308

Answer 13

So it would be 11/2 or -13/2 or -11/2 or -13/2 ?
