Nesterboy [21]

Answer:

x = $-\frac{3}{b}$

x = -1

Step-by-step explanation:

The given equation is,

-2(bx - 5) = 16

Dividing by (-2) on both sides of the equation,

$\frac{-2(bx-5)}{(-2)}=\frac{16}{(-2)}$

(bx - 5) = -8

By adding 5 on both the sides of the equation,

(bx - 5) + 5 = -8 + 5

bx = -3

Dividing by 'b' on both the sides of the equation,

$\frac{bx}{b}=\frac{-3}{b}$

x = $-\frac{3}{b}$

If b = 3,

x = $-\frac{3}{3}$

x = -1

Why should people be knowledgeable about equations and inequalities?

BartSMP [9]

Answer:

People should be knowledgeable about equations and inequalities because they are often used to solve day to day life problems.

Often times real life problems are modeled using equations and inequalities

Step-by-step explanation:

Inequalities are used often in real life, businesses use inequalities to control inventory, plan production lines, produce pricing models, and for shipping/warehousing goods and materials. Inequalities are used in engineering and production quality assurance.

An equation is the mathematical representation of those two things which are equal, one on each side of an 'equals' sign. Equations are useful to solve our daily life problem.
