Systems of equations with elimination: x-4y=-18 & -x+3y=11 | Equivalent systems of equations and the
The 1 and 2 subscripts really do not matter that much. This is asking you to find where the two equations intersect. *Elimination*: y= -3x+5 y=4x+12. Let's eliminate y by subtracting equation 2 from equation 1. => 0= -7x-7 => 7= -7x =>x= -1. Plug back in ...
