One Step
|x-4|=6
10 and -2
U=px, solve for x
X = p/U
|3x+1|=-2
No solution (absolute value cannot equal a negative number)
|3x+9|-10=-4
-1 and -5
|2x+12|=4x
X=6 (x=-2 is an extraneous solution)
C = 5/9(F-32), solve for F
F = 9C/5 + 32
The surface of Mercury is 427ºC. Using the formula
ºC = 9/5(ºF-32),
find the temperature of Mercury in degrees Fahrenheit.
800.6 ºF.
|3x+7|+7 = 5x
X=7 (x=0 is an extraneous solution)
N= -m+3d/b, solve for b
B = 3d/(N+m2)
