Transcript Example 17 Solve the pair of equations 2/𝑥 3/𝑦=13 5/𝑥−4/𝑦=−2 2/𝑥 3/𝑦=13 5/𝑥−4/𝑦=−2 So, our equations become 2u 3v = 13 5u – 4v = –2 Hence, our equations are 2u 3v = 13 (3) 5u – 4v = – 2 (4) From (3) 2u 3v = 13 2u = 13 – 3V u = (13 − 3𝑣)/2
Transcript Example 18 Solve the following pair of equations by reducing them to a pair of linear equations 5/(𝑥 −1) 1/(𝑦 −2) = 2 6/(𝑥 −1) – 3/(𝑦 −2) = 1 5/(𝑥 − 1) 1/(𝑦 − 2) = 2 6/(𝑥 − 1) – 3/(𝑦 − 2) = 1 So, our equations become 5u v = 2 6u – 3v = 1 Thus, our equations are 5u v = 2 (3) 6u – 3v = 1 (4) From (3) 5u v = 2 v = 2 ab = 17 4a 3b = 5 first one by 3 3a 3b = 51 4a 3b = 5 a = 46 b = 63 then 2^x = 46 , which is not possible in the real number set So for 2^x 3^y = 17 to be true, we would have add a "nonexisting number" to 3^y to get 17Algebra Solve by Addition/Elimination 2xy=3 3xy=17 2x y = −3 2 x y = 3 3x − y = −17 3 x y = 17 Add the two equations together to eliminate y y from the system 2 2
