Answer:
Mother is presently 34
Scott is 11
Step-by-step explanation:
Let the mother's age = x
Let the son's age = y
First Equation
x + y = 45
Second equation
3*(x + 5) - 9 = y+5 Add 9 to both sides
3(x + 5) = y + 5 + 9
3(x + 5) = y + 14 Remove the brackets
3x + 15 = y + 14 Subtract 14 from both sides
3x + 15 - 14 = y
3x + 1 = y
Put the first equation into the second equation
x + y = 45 Subtract y from both sides
y = 45 - x
Put this value for y into the second equation's results.
3x + 1 = 45 - x Add x to both sides
3x + x + 1 = 45
4x + 1 = 45 Subtract 1 from both sides
4x = 45 - 1
4x = 44 Divide by 4
x = 44/4
x = 11
x + y = 45
11 + y = 45
y = 34
i believe the answer is 42?
X would have to be less than 3.5
