Solving Equations
-93 = 7(-3k - 8) + 5
k = 2
Solving Equations
-5(8n - 4) - n = - 16 - 5n
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
-3(2-5x)+2 = 26
x = 2
2x - 4 = 3x + 2(x - 3)
x= 2/3
