(2)x+7y=10;3x-2y=7

Solve the following simultaneous equations. x+7y=10,3x-2y=7 .

Simultaneous equations x + 7y = 10, 3x - 2y = 7

Solve the following simultaneous equations. x + 7y = 10, 3x - 2y = 7

If 3x+5y=15 and x-2y=10 , what is the value of 2x+7y ?

Solve the following system of equations by matrix method : 5x+7y+2=0 4x+6y+3=0 5x+2y=3 3x+2y=5 3x+4y-5=0 x-y+3=0 3x+y=19 3x-y=23 3x+7y=4 x+2y=-1 3x+y=7 5x+3y=12

Solve: 2x-7y=7 , 3x+y=22

(i) x^(2) - 4x + 3 = 0 (ii) y^(2) - 7y+10 = 0

If 3x-7y=10 and xy=-1, find the value of 9x^(2)+49y^(2)
