To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.

c - 6 < -1 + 7c
c < -1 + 7c + 6
c - 7c < -1 + 6
-6c < 5
c < \( \frac{5}{-6} \)
c < -\(\frac{5}{6}\)

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(7a)(8ab) - (6a²)(6b)
(7 x 8)(a x a x b) - (6 x 6)(a² x b)
(56)(a¹⁺¹ x b) - (36)(a²b)
56a²b - 36a²b
20a²b

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

5a - 8a = -3a

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses:

(y + 3)(y + 2)
(y x y) + (y x 2) + (3 x y) + (3 x 2)
y² + 2y + 3y + 6
y² + 5y + 6
