Question

solve:65x - 14y =9 and 91x-15y = 31

by elimination method
​

Answer 1

Answer:

Step I: Let the two equations obtained be

a1x + b1y + c1 = 0 ….(1)

a2x + b2y + c2 = 0 ….(2)

Step II: Multiplying the given equation so as to make the co-efficients of the variable to be eliminated equal.

Step III: Add or subtract the equations so obtained in Step II, as the terms having the same coefficients may be either of opposite or the same sign.

Step IV : Solve the equations in one varibale so obtained in Step III.

Step V: Substitute the value found in Step IV in any one of the given equations and then copmpute the value of the other variable.
