For this case, the first thing we must do is define variables:
x: Jane's age
y: Helen's age
By writing the system of equations we have:
y = x + 8
y-20 = 3 (x-20)
Solving the system we have:
x = 24
y = 32
Answer:
Jane is 24 years old
Helen is 32 years old
the equation for Jane would look like:
x + 8 = 3 (x-20) + 20
Answer:
4.325 x 
Step-by-step explanation:
Scientific notation
This means that the decimal in the number 4.325 is carried to the right 9 times and the empty spaces are the 0s in the answer
X + 367 = 860
x = 860 - 367
x = 493
The dog had 493 bones to start with.
