What is the solution of |3x-2|=7 ?
a. x = 5/3 or x = 9
b. x = - 5/3 or x = 3
c. x = - 5/3 or x = 5/3
d. x = 5/3 or x = 3
separate the absolute value equation into two parts-one + the other -
3x-2=7 and 3x-2=-7
add 2 to both sides (on each equation)
3x=9 and 3x=-5
divide 3 from both sides (on each equation)
this leaves you with
x=3 and x=-5/3
the answer is b.
Hope this helps!
