Solve the system by graphing x y = 3 x y = 1 The idea is to graph both lines and find the point where they cross, or intersect Get three points on the first line x y = 3 Pick an arbitrary value for x or yGRE All you do need to know about the GRE Test GRE Prep Club for the GRE Exam The Complete FAQ Search GRE Specific Questions Download Vault Posting Rules QUANTITATIVE VERBAL FREE Resources GRE Prep Do similar operations on xy=5 as I explained for xy=3 Perform operations on the given equation so that the equation transforms to y=mxb form as follows xy=5 subtracting y and 5 from both sides we get x5 = y or y=x5 This can also be written as y=1*x5 This is now in the form y=mxb where m=1 and b=5 Now mark the point 5 on the y axis

Xy30 pokemon-So to find the expansion of (x − y)3, we can replace y with (−y) in (x y)3 = x2 3x2y 3xy2 y3Since is too small and is too big, one of the numbers (call it y) must be 4 And that leaves , so x=3 In other words, (3,4,5) is the only solution using positive integers, up to permutation If you relax that to allow zero, then (0,0,6) is a solution
