A letter or symbol that represents an unknown value
Variable
For 11s + 8 = 9 , this is the next step
subtract 8 from both sides
5q - 4q = 9
q = ?
q=9
-90 = -10t
t=7 or t=9
t=9
9y + 4y
13y
What you do when you simplify an expression.

For 3d = 15, the next step is
divide both sides by 3
17t +2t + 3t - 17t = 10
t = ?
t = 2
3u - u = 8
u=3 or u=4
u=4
8 - g + 9g + 7g
15g + 8
This also means to evaluate an equation.
Solve
For 2(t+1) = 10, what is the next step
divide both sides by 2
7q + 17q - 14q - 8q = 14
q = ?
q = 7
77 = 7(t +12)
t=-2 or t=-1
t=-1
8h + 2h + 5h + h + 6h
22h
These are the five steps to solve an equation:
1) Combine _____ Terms
2) Eliminate the ________
3) _______ the Variable
1)Like
2)Coefficients
3)Isolate
s = this when you subtract 5 from both sides for
s + 5 = 9
s=4
17s + 3s + 2s - 14s - s = 7
s = ?
s = 1
-9t = -6t - 9(t +6)
t=-3 or t=1
t=-3
-3s + -8s + -5s + -6s + 4s
-18s
This is the difference between and Expression and an Equation
