Terms
Variable - is a letter that represents an unknown number in algebra (ex. q, x, z, t)
Constant - is the integer in an expression or equation (ex. x +6)
Expression - is a pattern; has multiple or infinite answers (ex. 2x)
Equation - has an equal sign; only one possible answer (ex. 2x = 6)

One Step Equations
Steps for Completing Equations
1. Isolate variable - get rid of constant
2. Cancel using opposite; use a zero pair for constant
3. Balance - do the same on other side of the equation
4. Verify - solve to equality
