1-6 solving complex linear equations

planning a solution

know your enemy- does the equation have distribution, combine like terms, variables on the same side of the equal sign?
Remember, plan what you are going to do and trust your skills

Multiple Choice

What is the only step you can not do first.

5-3\left(2x+4\right)-2=3\left(7-x\right)-5\left(2x+7\right)-12

multiply -3(2x+4)

do 5-3

add 2 to both sides of the equation

add 12 to both sides of the equation

5−3(2x+4)−2=3(7−x)−5(2x+7)−12

A good plan is to always distribute first
5-6x-12-2=21-3x-10x-35-12
then combine like terms
-6x-9 = -13x-26
get the variable on 1 side of the equal sign
7x-9 = -26
get rid of the constant on same side as the variable
