y=x+3 7x+5y=9

y=x+3 7x+5y=9

This is a system of two linear equations with two variables, x and y. The goal is to find the values of x and y that satisfy both equations simultaneously.

2x+3y=-5 3x-4y=18

2x+3y=-5 3x-4y=18

This is a system of two linear equations with two variables, x and y. The goal is to find the values of x and y that satisfy both equations simultaneously.

11x + 5y = 78 5x + 11y = 66

11x + 5y = 78 5x + 11y = 66

This is a system of two linear equations with two variables, x and y. The goal is to find the values of x and y that satisfy both equations simultaneously.

2017x+2019y = 8070 2019x+2017y = 8074

2017x+2019y = 8070 2019x+2017y = 8074

This is a system of two linear equations with two variables, x and y. The goal is to find the values of x and y that satisfy both equations simultaneously.

x + 3y = 4 -y+2z=-4 -2y-2z = 3

x + 3y = 4 -y+2z=-4 -2y-2z = 3

This is a system of three linear equations with three variables, x, y, and z. The goal is to find the values of x, y, and z that satisfy all three equations simultaneously.
