No solution

Answer 1

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

Answer 2

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

Answer 3

mkay ill try

Answer 4

thank you :)

Answer 5

still don't get this :((

Answer 6

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

Answer 7

theres no solution right

Answer 8

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

Answer 9

ohhhh mkay thanks very much man :)
