Solve the absolute value equation<br> algebraically: 3|2x - 3| + 2 = 3

kupik [55]

Answer:

$3 |2x - 3| = 1$

$3 |2x - 3| = 1 \\ 6x - 9 = 1 \\ 6x = 10 \\ x = \frac{10}{6} = \frac{5}{3}$

$3 |2x - 3| = - 1 \\ 6x - 9 = - 1 \\ 6x = 8 \\ x = \frac{4}{3}$

$x = \frac{5}{3} x = \frac{4}{3}$

I am sorry but I am not sure of this :(
