I tryed doing this question but i keep doing it wrong. Solve |2 - 3x| = 7. A. {-5/3, 3} B. {-15, 3} C. {-3, 5/3} D. {-3, 15}
it would help if you clicked good answer after people have answered it
before you do anything, you have to get the numbers in the absolute value sign alone. In this equation, you do. So now you can just solve like a regular algebra problem. First problem will have what's NOT in the absolute value sign negative and positive. so first, you can do a problem where 7 is positive, and another problem where 7 is negative so 2-3x = -7 solve like a regular algebra problem -3x=-9 x=3 now make 7 positive 2-3x=7 solve regularly -3x=5 x= -5/3
but it loooks like it's not on your list but im pretty sure it's right http://www.wolframalpha.com/input/?i=%7C2+-+3x%7C+%3D+7
\[|3x-2|=7\] \[3x-2=7\text{ or } 3x-2=-7\] \[x=3 \text { or } x=-\frac{5}{3}\]
