Answer» Step-by-step explanation:Equations reducible to pair of linear equations in 2 variables Sometimes we come across pair of equation which are not linear but can be REDUCED to linear form by MAKING some suitable substitutions. E.g. 2/X + 3/y = 13 & 5/x + 4/y = 2 This equation is not a linear equation, but if we substitute 1/x with a & 1/y with b, then the equation becomes 2a+ 3b =13 & 5a + 4b = 2. This is now a pair of linear equation in 2 variables. After finding the values of variables a & b, we can EASILY find x as 1/a & y as 1/b.hope it helps you |
