A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. the '4' in 4x or 4y).
Coefficient
28 = 23 – x
x= -5
Write the equation AND solve:
You buy 3 books that each cost the same amount and a magazine, totaling $55.99. The magazine cost $1.99. How much does each book cost?
3b + 1.99 = 55.99
Solve:
3b + 1.99 = 55.99
-1.99 -1.99
3b = 54.00
3b/3 = 54.00/3
b = 18 Each book costs $18.00.
