Answer:
1. x = 3 or x = -8
2. x = -2 or x = 10
Step-by-step explanation:
1. |2x + 5| = 11
2x + 5 = 11 Or 2x + 5 = -11
-5 -5 -5 -5
----------------- -----------------
2x = 6 2x = -16
/2 /2 /2 /2
----------------- -----------------
x = 3 x = -8
2. 3|x - 4| + 1 = 19
3|x - 4| + 1 = 19
-1 -1
----------------------
3|x - 4| = 18
/3 /3
----------------------
|x - 4| = 6
x - 4 = -6 Or x - 4 = 6
+4 +4 +4 +4
----------------- -----------------
x = -2 x = 10
Answer:
1. x = 3
2. x = 10
Step-by-step explanation:
[tex]1. \: \: (2x + 5) = 11 \\ 2x + 5 = 11 \\ 2x = 11 - 5 \\ 2x = 6 \\ x = \frac{6}{2} \\ x = 3 \\ [/tex]
[tex]2. \: \: \: 3(x - 4) + 1 = 19 \\ 3x - 12 + 1 = 19 \\ 3x - 11 = 19 \\ 3x = 19 + 11 \\ 3x = 30 \\ x = \frac{30}{3} \\ x = 10 \\ [/tex]
