Name of the type of math where numbers and symbols are used to formulate expressions and equations.
Algebra
-16 = x/2
x= -32
(x/3)+12=-3
x= -45
Solving Equations
-93 = 7(-3k - 8) + 5
k = 2
Solving Equations
-5(8n - 4) + 4n = - 16
n = 1
A numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. the '4' in 4x or 4y).
Coefficient
w/4 = -8
w = -32
25 = 1/4n - 3
n = 112
Steps:
25 = 1/4n - 3
+ 3 +3
28 = 1/4n
now multiply by 4 or (4/1), combine like terms and simplify 4 * 1/4n.
4 * 28 = 4 * 1/4n
112 = n
Write the equation:
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?
Solve for 100 BONUS points.
3b + 1.99 = 55.99
BONUS: 3b + 1.99 = 55.99
-1.99 -1.99
3b = 54.00
3b/3 = 54.00/3
b = 18 Each book costs $18.00.
- 4 = 3x + 2(x - 3) - 2x
x= 2/3
