Question

Solve |2y - 2| = 15

Answer 1

Split it into two equations and solve for y.
\[|2y - 2| = 15 \implies\]\[2y - 2 = 15 ~~~~~~or~~~~~~2y - 2 = -15\]Can you solve for y in both equations?

Answer 2

yes

Answer 3

What do you get?

Answer 4

13 and -13

Answer 5

How so?
Her's what the first one looks like.
\[2y - 2 = 15\]\[2y = 17\]\[y = 17/2~or~8.5\]

Answer 6

o ok

Answer 7

Can you do the second equation though now that you see how to do the first one?

Answer 8

yes i got negative 13

Answer 9

hmm

Answer 10

Then you have to do what?
\[2y = -13\]\[y = ?\]

Answer 11

the first step would be to add 2 to both sides to make
\[2y-2=-15\] into
\[2y=-13\] but that is \(2y\) and not \(y\)
one more step
