Respuesta :
2 |d+5| - 1 < 3
Start by adding 1 to both sides...
2 | d + 5 | < 4
Divide both sides by 2
| d + 5 | < 2
Now make to sections...
d + 5 < 2 or d + 5 > - 2
Subtract both sides 5
d < - 3 or d > - 7 is the answer
Or you can write is as - 7 < d < - 3
Start by adding 1 to both sides...
2 | d + 5 | < 4
Divide both sides by 2
| d + 5 | < 2
Now make to sections...
d + 5 < 2 or d + 5 > - 2
Subtract both sides 5
d < - 3 or d > - 7 is the answer
Or you can write is as - 7 < d < - 3
2(|d+5|)−1<3
Lets break this down using the order of operations.
Step 1: Add 1 to both sides.2(|d+5|)−1+1<3+12(|d+5|)<4
Step 2: Divide both sides by 2.2(|d+5|)2<42|d+5|<2
Step 3: Solve Absolute Value.
If you don't know what the absolute value is then...Wow|d+5|<2We knowd+5<2andd+5>−2d+5<2(Condition 1)d+5−5<2−5(Subtract 5 from both sides)d<−3d+5>−2(Condition 2)d+5−5>−2−5(Subtract 5 from both sides)d>−7
