y*49/39 = 7/13 => y = 3/7
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
The closest to a solution you can come is:2x + y = 39
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
y=-39
-9x + y = 39 y = 9x + 39 The y-intercept is where x = 0 Therefore the y intercept is where: y - 9(0) = 39 y = 39 The y intercept is 39 The x-intercept is where y = 0 Therefore the y intercepet is where: 0 - 9x = 39 - 9x = 39 9x = - 39 x = -39/9
OK, so-3y + 15 - y = 39-3y + 15 - 15 - y = 39 - 15-3y -y = 24-4y = 24-y = 6y= -6.Hope this helps!

The transition metal with 39 protons is Yttrium (Y), which has chemical symbol Y and atomic number 39.
39 * 406 = 15834
"Y over 39" ... usually written as y/39 ... is neither a question nor a problem, and needs no answer or solution. It's nothing but a number, which you can identify immediately, as soon as you know the numerical value of 'y'.
7y + 18 = 39 Therefore, 7y = 39 - 18 = 21 y = 21/7 y = 3
x + y = 39 x - y = 11 _________ 2x = 50 x = 25 y = 14
let x be one number and y be the other The first thing given is that x is 3 less than twice y so x=2y-3 and x+y=39 so x=39-y and substitute this into the first equation a 39-y=2y-3 42=3y y=14 and x=39-14 or 25 Answer x=25 and y=14 Now lets check it 25 is 3 less than 2x14 (YES) 14+25=39 (YES) Done
The closest to a solution you can come is:2x + y = 39
