how to solve 3 simultaneous equations

Simultaneous Equations - Consider a linear equations in two variables , say, 3x - 2y = 5. It has an infinite number of solutions, some of these are x = 0, Consider a linear equations in two variables , say, 3x - 2y = 5. It has an infinite ..

Solve the following Systems of linear equations : 1. If one number is thrice the other and their sum is 60, find the numbers. 2. Find the fraction which becomes 1/2 when the denominator is increased by 5 and is equal to 1/3 when the numerator is diminished by ..

The solution is x = -9 and y = -2. Solve 43x + 31y = 241 (i) 31x + 43y = 277 (ii) By adding (i) and (ii), we get 74x + 74y = 518 x + y = 7 (iii) By subtracting (ii) from (i) 12x - 12y = -36 or x - y = -3 (iv) By adding (iii) and (iv) 2x = 4 x = 2 Substituting x = 2 in (iii), we g..

Solving two equations simultaneously means to find the common solution of both the equations, i.e., a solution which satisfies both the equations. The following two methods are used to find a solution: (a) Method of elimination (b) Method of s..
