Answer:
x=-8 x=-12
Step-by-step explanation:
Divide 3 to both sides
|x+10|=2
Set x+10 to equal 2 and -2
x+10=2 x+10=-2
solve both equations
x=-8/-12

Answer:
a = 132; b = 12; c = 36
Step-by-step explanation:
a = b + 120
b = b
c = 3b
a + b + c = 180
(substitute these into the above equation)
b + 120 + b + 3b = 180
5b + 120 = 180
-120 -120
5b = 60
/5 /5
b = 12
(substitute b back into the first equations)
a = (12) + 120 = 132
b = (12)
c = 3(12) = 36
(check: 132 + 12 + 36 = 180)
