5x+2y=-3;x+5y=4

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

In the algebraic expression 5x^2y+7x y^2-3x y-4y x^2, we have 5x^2y and -4y x^2 as like terms, whereas 7x y^2 and -3x y are unlike terms.

Subtract : 3/2x^2y+4/5y-1/3x^2y z\ from \ (12)/5x^2y z-3/5x y z+2/3x^2ydot

5x+2y=4 7x+3y=5

Subtract: x^2y-4/5x y^2+4/3x y\ from 2/3x^2y+3/2x y^2-1/3x y

3 x + 2y = 12 , 5x - 2y = 4 .
