One number added to twice another number is 13. Four times the first

Karo-lina-s [1.5K]

Let's call the first number x, and the second number y. Putting what you have said into equation form:

$x+2y=13
\\\\4x+2y=-2
$

Subtracting one equation from another gives:

$x+2y=13 \\-(4x+2y=-2)

\\\\-3x=15
\\x=-5$

If x = -5,

$x+2y=13
\\(-5)+2y=13
\\2y=18
\\y=9$

So the first number is -2, the second number is 9
