Answer:
x = 4 and x = -9
Step-by-step explanation:
|2x+5| = 13
(2x + 5) = 13
2x = 8
x = 4
-(2x + 5) = 13
-2x - 5 = 13
-2x = 18
x = -9

Answer:
-20a - 65 = -104 for a = 2.7
-6x + 52 = 45 for x = 1 1/6
Step-by-step explanation:
-20a - 50 for a = 2.7
Insert 2.7 in for a.
-20(2.7) - 50 = -54 - 50 = -104
-6x + 52 for x = 1 1/6
Insert 1 1/6 for x.
-6(1 1/6) + 52 = -7 + 52 = 45
