1)one number is four more than a second number. Twice the second is three more than the first. Find the numbers.
2)four times one number minus a second is 11, and the sum of the numbers is 14. Find the numbers.

let one number (the first ) be x
let the second number by y
Just translate the English into Math , after all Math is just a language
"one number is four more than a second number" > x = y+4
"Twice the second is three more than the first" > 2y = x+3
so lining them up
x  y = 4
x  2y = 3
subtract:
y = 7
then from x = y+7
x = 11
The first number is 11, the second is 7
check:
is 11 four more than 7 ? YES
is twice 14 three more than 11 ? YES
I am right!!!
Try the second the same way, show me your work
