Answer:

In order to solve this algebraic expression, you need to get the variable x by itself

Step 1: subtract 4 from each side

4-4+7x=-24-4 (4-4=0, those cancel out) (-24-4=-28)

7x=-28

Step 2: divide both sides by 7

7x/7=-28/7 (7x/7=x) -28/7=-4)

Your final answer would be x=-4

Hope this helps ;)

Answer:

-3

Step-by-step explanation:

Subtract 4 from both sides

7x= -24-4

7x= -28

Then divide both sides by 7

x= -28/7

x= -3

Hope this helps!

hichkok12 [17]

Answer:

14

Step-by-step explanation:

we are solving 15 + |-3| - 4

anything inside |   | means it's absolute value.

absolute value means that even if it is a negative number inside, it will change to positive. if it is a positive number inside, it will stay the same.

so |-3| is 3.

15 + 3 - 4

18 - 4 = 14.

Which of the following is a solution of x² + 14x + 112 = 0? If necessary, round to the nearest hundredth.
Readme [11.4K]
To determine the solution of the quadratic equation, use the quadratic formula which states that,
                                x = ((-b  +/- sqrt (b² - 4ac)) / 2a
From the equation, a = 1, b = 14, and c = 112. Substituting these to the quadratic formula,
                               x = <span>((-14  +/- sqrt (14² - 4(1)(12)) / 2(1) = indeterminate
Thus, the equation does not a real number solution. </span>
