#2 | The _____ of a term that has a variable is the number part of the term | Coefficient |
#3 | A term that has a number, but no variable, is a ______ | Constant term |
#4 | Identify the coefficients: -2x + 3x - 7 | -2 and 3 |
#5 | Identify the constant terms: -5 + 4x - 2y - 6 | -5 and -6 |
Combining Like Terms | ||
#1 | 5x + 2x - 3 | 7x - 3 |
#2 | -2x + 3x - 4 - 2 | x - 6 |
#3 | -5 + y - 6 + 3x - 5x | -11 + y - 2x |
#4 | -4y + 2x + 7y - 1 | 3y + 2x - 1 |
#5 | 7n - x + 4x + 3n - 2 | 10n + 3x - 2 |
Distributive Property | ||
#1 | 2(x + 3) | 2x + 6 |
#2 | -3(n - 5) | -3n + 15 |
#3 | z - 3(z + 1) | -2z - 3 |
#4 | 2x + 4(x + y - 5) + x | 7x + 4y - 20 |
#5 | 2 - x(3 + y) - 6x | -9x - xy + 2 |
Solve for x | ||
#1 | 2x - 3x + 2 = 4 | x = -2 |
#2 | 3(x + 2) = 18 | x = 4 |
#3 | -2(x - 4) - x = 23 | x = -5 |
#4 | 3 + 5(x - 4) = 33 | x = 10 |
#5 | 2(x - 4) - 4(x + 2) = 18 | x = -15 |
