The sum of two numbers is 35. The second number is four times the first number.Work out the 2 numbers

2 answers

First number = x
Second number = y = 4 times the first = 4x

x + y = 35
=> x + 4x = 35

Now, can you solve for x?
Keeping it simple,
x+y=35
y=4x

simpler terms, x=4x=35 (5x = 35)
divide that we get x = 7.
4x = 7x4 = 28.
7 and 28 are the two numbers.

We can check that by doing 7+28, which equals 35.
