im far behind being far behind i need majore help please :(

campbell_st · Answer

start by adding 4 to both sides of the equation and you get

|2x + 6| = 24

since its an absolute value, you will need to solve 2 equations

2x + 6 = 24                    and 2x + 6 = -24 

just solve both for x

mkay ill try

thank you :)

anonymous · Answer

still don't get this :((

campbell_st · Answer

you just need to practice... and with absolute value questions like this just get it to the absolute value is equal to a number

then solve the positive and negative version

anonymous · Answer

theres no solution right

campbell_st · Answer

there are 2 solutions 


subtract 6 from both sides of each equation 

2x = 18                     and     2x = -30

now divide each equation by 2 to get the answers
