Question

Solve the pair of linear equations in two variables 3x+4y=25 and 5x-6y=-9

Answer 1

There are infinite solutions for this equation.  1) 3x + 4y=25  (If x= 3 then)     = (3×3) + 4y=25     = 9+4y=25     = 4y=25-9     = 4y=16     = y=16/4     =y=4  2) If x = 3 Then, =(5×3)-6y=-9 =15-6y=-9 =-6y=-9-15 =-6y=-24 = y=-24/-6 = y=4  I hope this will help you.
