Answer:
x= 11/12
Step-by-step explanation:
12x - 1 = 10
12x = 10 + 1
12x = 11, divide 11 by 12
you can't divide it evenly so leave it as a fraction.
Answer:
55 years old
Step-by-step explanation:
1. Born 5 years after her husband
h -5 = c
twice as old as son
h-5 /2 = s
s = 25
h -5 /2 = 25
h-5 = 50
50+5 = 55
It would simplify down to (2m^3n^4)/7
3x + 9 = 2x + 12
-2x -2x
1x +9 = 12
-9 -9
x = 3
