What is a variable?
Write an example of one
A Variable is a letter or symbol whose value can change
Use the order of operations to solve
(7+3) x 4 - 3
37
3(5x + 2)
15x6
3a^2+ 3b x 4a - b
3a^2+ 2b x 4a
4( 3b - 3) + 15 + 6b^2 b = 2
75
Label the Variable, constant, and coefficient
7x+2
Variable = x
Constant = 2
coefficient = 7
18/3 +2 x 6

4(x^2+3+ 5)
4x^2 + 12+20
4w ^2+ 6c ^3+ 6w^2 - 3w + 2c^2
10w^2 + 6c^3 - 3w + 2c^2
4(2c + 3b) + 5b - 2c c = 2 b = 4
