The sum of two numbers is 13. The sum of the greater number and twice the smaller number is 23. Find the numbers.
Can someone show me how to do it. I know the 1st equation but not the 2nd equation.

x=greater number
y= smaller number
x+y=13
x+2y=23
Since adding a y adds 10 y=10
If you plug 10 in for y you get x+10 = 13. This means x = 3
y= smaller number
x+y=13
x+2y=23
Since adding a y adds 10 y=10
If you plug 10 in for y you get x+10 = 13. This means x = 3
