-2x plus 3y equals 1
-3y + z = 12
x = 3 and y = 0
Multiply the bottom equation by -1
Multiply the top equation by 3 and the bottom equation by 2. (-4, 1)
The equation for 3y + 3y = -1 is 3y + 3y = -1.
-2x plus 3y equals 1
-3y + z = 12
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
It's an hyperbola equation.
3y=4x+9.....-4xAnswer: 4x-3y=9
x = 3 and y = 0
It is one linear equation in two unknown variables.
Multiply the bottom equation by -1
3y + 2y + 4 + 1 = 805y + 5 = 805y = 75y = 15
