Question

Choose the two equations you would use to solve the absolute value equation below. Then solve the two equations.

|2x + 5| = 3
A.
2x + 5 = 3 and 2x + 5 = –3; {–1, –4}
B.
2x + 5 = 3 and 2x + 5 = –3; {1, –4}
C.
2x – 5 = 3 and 2x + 5 = –3; {–1, 4}
D.
2x – 5 = 3 and 2x + 5 = –3; {–1, –4}

Answer 2

Just like this previous one:

\[\large{|x+a| = b}\]

\[\large{\implies x+a = b ,x+a = -b}\]

I can extend it to this:

\[\large{|cx + a| = b}\]

\[\large{\implies cx+a = b, ~~cx+a = -b}\]

Answer 3

What do you think the answer should be ?

Answer 4

I think its B

Answer 5

Your equations are correct. Check the values of x you will get from them

Answer 6
