If: 3x+2y = 5x+2y = 14
Then: 3x+2y = 14 and 5x+2y =14
Subtract the 1st equation from the 2nd equation: 2x = 0
Therefore by substitution the solutions are: x = 0 and y = 7

What are the solutions to the simultaneous equations of x -2y equals 1 and 3xy -y squared equals 8 showing all appropiate work with answers?
If: x-2y = 1 and 3xy -y^2 = 8 Then: x = 1+2y and 3(1+2y)y -y^2 = 8 Hence: 3y+6y^2 -y^2 = 8 => 5y^2 +3y -8 = 0 Solving the above quadratic equation: y =1 or y = -8/5 Solutions by substitution are: when y=1 then x=3 and when y=-8/5 then x=-11/5
