Help ASAP step-by-step please So I can understand it.
Rearrange the second equation as y = 4 - x. Substitute this into the first equation:
4 - x = x2 - 3x + 4
This simplifies to. x2 - 2x = 0
This factors as. x(x - 2) = 0, so x = 0 or x = 2
Substitute these back into y = 4 - x to find the corresponding values of y.
