y=2x+8
Solve: y=(x-2)(x+5) using FOIL method (first, outside, inside, last) to get: y=x^2+5x-2x-15 y=x^2+3x-15
5y-6x=3z
Algebra Problem: 2y=x+2z-4; x=4z-4; z=y+2 y=1/2x+z-2 y=1/2(4z-4)+z-4 y=2z-2+z-4 y=2(y+2)+(y+2)-4 y=2y+4+y+2-4 y=3y+2 -2y=2 y=-1 z=-1+2 z=1 x=4(1)-4 x=4-4 x=0 y=-1, z=1, x=0
Algebra Equations Rock!!
solve: (x+1)(x-1) using the box method x +1 x x^2 +x -1 -x -1 to get x^2+x-x-1 x^2-1
