6+8=14
-9+4= -5
6j + 84
-6y-30
36m-18

3. An algebraic expression is in simplest form if it has no like terms and no parentheses.
There are not any parentheses so we do not have to distribute. Next we look for like terms and add them. Now the expression is simplified.
-5x+1
Since we have parentheses we have to distribute first.
m + 3n + 12m
m + 3n + 12m
After distributing add your like terms. Now the expression is simplified.
13m + 3n

4. Practice 1). 9y + 8 – 8 2). 2x – 5 -4x + 8 3). 5 – 3(y + 7)
4). 3x + 2y + 4y
5). x + 3(x + 4y) 9y
-2x+3
-3y-16
3x+6y
4x+12y
