Variables on both sides
Remember the goal
Getting them on one side: Isolating the variable
Let's try this one write it down and on the next slide, we'll work it out together
2x - 14 = -5x + 7
6
1) Simplify if possible.
2) Use inverse operations to get all variables on one side.
3) Use inverse operation to isolate a variable
2x - 14 = -5x + 7
Let's work it out
7
Math Response
Solve this one!
13x = 9x + 8
8
Math Response
And another one!
14x -21 = 17x
9
Simplifying First!
If there are multiple "like terms" combine them!
Let's try one!
5x + 11 - 3x = 8 + 4x - 3

Math Response
Solve the following: Write your answer as
a=
5 + 7a = 6a - 13 - 2a
