davids mother is 30 years older than him. her age will be four times that of david eight years later. how old is david now?
with that ?
Oh my:
d+30+8 = 4(d+8)
d + 38 = 4 d + 32
3 d = 6
d = 2
mom is 32 and David 2
in 8 years mom will be 40 and David 10
d+30+8 = 4(d+8)
solve for d.
Idk, need help
To find out David's current age, we can set up an equation based on the given information.
Let's assume David's current age is "x" years. According to the information given, his mother is 30 years older than him. Therefore, his mother's current age would be "x + 30" years.
The problem also states that his mother's age will be four times that of David's age eight years later. So, David's age in 8 years would be "x + 8" years, and his mother's age in 8 years would be "4(x + 8)" years.
Now let's set up the equation:
x + 30 + 8 = 4(x + 8)
Simplifying the equation:
x + 38 = 4x + 32
Subtracting "x" from both sides:
38 = 3x + 32
Subtracting 32 from both sides:
6 = 3x
Finally, dividing both sides by 3:
x = 2
Hence, David is currently 2 years old.
