Addie Ponder


 * 1) 1- To simplify is to make the number as small as it can go. (5*2+3*4) To solve is to complete what the question is asking you. (2+4=6), To evaluate is to replace a variable with a number. (3x+2=3(4)+2)

-2x+3y, x=-2 y=-4, to evaluate this you would do -2 times -2 and you get 4, then you would do 3 times -4 and that is -12 so then it os 4+-12= -8
 * 1) 2- -2x+12-3x+4-3y, to simplify first you would combine -2x and -3x= -5x then you would combine 12 and 4=16 so then you have -5x+16-3y
