Question

Solve. |2x + 4| - 5 = 6

Answer 1

solve for x when

2x + 4 - 5 = 6

AND

2x + 4 - 5 = -6

Answer 2

add 5 to both sides and solve
\[|2x+4|=11\]
\[2x+4=11\] or
\[2x+4=-11\] etc

Answer 3

careful here
have to add 5 to both sides first

Answer 4

oh...it's not the same? i assumed they were :/

Answer 5

@lgbasallote try it and see. first one will not make a difference but there is a difference between
\[2x + 4 - 5 = -6\]
\[2x-1=-6\]
\[2x=-5\]
\[x=-\frac{5}{2}\] and
\[2x+4=-11\]
\[2x=-15\]
\[x=-\frac{15}{2}\]

Answer 6
