Solve the equation:

 $-72=6\left(x-2\right)$  

• 10

• 35/3

• -10

• other

When solving an equation with variables on both sides, the goal is

• move all variables to one side & all constants to the other side by doing the opposite operations

• add all terms together

• divide away all numbers

• combine the x-terms & the constants into one term

What is a possible first step to solve this equation:

-11 - 3x = 44 - 2x

• Add 3 to both sides

• Subtract 11 to both sides

• Add 11 to both sides

• Add 2 on both sides.

What is another possible first step to solve this equation:

-11 - 3x = 44 - 2x

• Add 3 to both sides

• Add 2 to both sides

• Subtract 2x to both sides

• Add 2x on both sides.

Solve the equation:

-11 - 3x = 44 - 2x

• 33

• 11

• -55
