Answer:
a - 8
Explanation:
7a−6+3−8a−(−2a+5)
Distribute the Negative Sign:
=7a−6+3−8a+−1(−2a+5)
=7a+−6+3+−8a+−1(−2a)+(−1)(5)
=7a+−6+3+−8a+2a+−5
Combine Like Terms:
=7a+−6+3+−8a+2a+−5
=(7a+−8a+2a)+(−6+3+−5)
=a + −8
Answer:
= a − 8
Answer:
1. x = 3 or x = -8
2. x = -2 or x = 10
Step-by-step explanation:
<u>1. |2x + 5| = 11</u>
2x + 5 = 11 Or 2x + 5 = -11
-5 -5 -5 -5
----------------- -----------------
2x = 6 2x = -16
/2 /2 /2 /2
----------------- -----------------
x = 3 x = -8
<u>2. 3|x - 4| + 1 = 19</u>
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
