Answer:

Step-by-step explanation:

All you have to do is follow this order while working a problem!

Example 1:

If a = 4 and b = 5, what is ab – 2b?

Since there are no parentheses or exponents,

you first plus in the values for a and b and multiply those together.

(4 ´ 5) You get 20.

Then, you multiply 2b or (2 ´ 5 )which gives you 10.

Last, you subtract the second answer from the first (20 -10),

which gives you 10!

Example 2:

Evaluate 6x / 4 when x = 6.

Because multiplication and division are equal in the order of operations, you solve the problem by reading it from left to right like one would read a book.

6 x 6 = 36.

You then divide that number by 4.

The correct answer is 9.

Answer:

Step-by-step explanation:

basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below

If the linear equation with one variable is x / 4 + 2 = –2. Then the value of x will be negative 16.

<h3>What is simplification?</h3>

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The equation is given below.

x / 4 + 2 = –2

Solving for x, we have

x / 4 + 2 = –2

x / 4 = – 2 – 2
