-simplify-replace it with an equivalent expression having as few terms as possible ex: 2x+5+4x simplifies to 6x+5 -solve- is to find out the answer of a problem ex: 2+4=6 -evaluate-replace each variable with a number, and then follow the order of opperation ex: 3x+2 for x=4
 * 1) 1. what means...

1.-walk through the steps of -2x/+12/-3x/+4/-3y -first you seperate the #s by putting bars between the spaces - next you fins the like terms= -2x,-3x,12,4 -then match the like terms= -2x,-3x 12,4 - next combine the like terms= -2x-3x=1x 12+4=16 -then put the problem back together 1x+16-3y - then find the rest of the like terms... if there aren't any in this case them that is your answer A= 1x+16-3y
 * 1) 2-steps through simplifying and evaluating

2. walk through the steps of evaluating with this problem -2x+3y, x=-2 y=-4 -first you replace the variables with the given number -2(-2)+3y(-4) -then you multiply the numbers in to the number next to them -2(-2)= 4 3y(-4)= -1y -now put the problems back together with the correct answer 4-1y -since they are not any like terms then that is your answer A= 4-1y

Equations:1. Freedom paid $29.97 for 9.8 gallons of gas for her car. How much would she pay for 11.8 gallons? 2. Casey paid $109.89 for staying 4 days in a hotel. How much would she pay if she stayed there for 3 more days?
