Well, obviously the speed of the plane must be greater than the speed of the wind, so in x-y = 112 x must be the plane's speed and y the wind's speed so sub y = 23 into x+y = 158 x+23=158 x = 155 ^that's what you said.. you wrote 155 not me..?
oh okay thanks! I got 135 not 155... but does that apply everytime or is that just a shortcut type of thing? it's not wrong if I subtract x+y=158 and x-y=112 right?
oh okay thank you so much! i also have another question: does it matter whether we add or subtract simultaneous equations? do we have to either add or subtract or are both fine?
how come if I do: x+y=158 x-y=112 and then i subtract them: 2y=46 -> y=23 why do I get the speed of plane as 23?
