The goal of solving a one, two, or multi-step equations is to:

• Find the coefficient

• Find the value of the variable

• Find the constant

• Be confused

CCSS.7.EE.B.4A

In order to solve an equation, we must get the variables on one side of the equation, and the constants on the other side.

• False

• True

What is the first step you should take to solve this problem?

1 + 4n - 6n = 1 - 8n

• subtract 8n to both sides

• multiply 6n to both sides

• combine the like terms 4n + -6n
