So we take whatever is in the freshly creation and just substitute that into the second. So what we have is five y, minus nine. Minus two y equals negative. Six. This gives me three my equals 15 and therefore, why equals five on if we plugged us back into any of the even equations. So let's say the 1st 1 I get X equals five times fine, minus time. So this is 25 minus nine, and that gives me 16. So my solution is 16. Come if I
