Answer:

For the first equation put in 4
For the second equation put in -12

(See below for writing)

Step-by-step explanation:

1. when you distribute 3 you multiply by three, so you have to do the opposite to find your answer.12/3=4

2. You just have to rewrite it. If you made the second one a positive equation, you would have 3x+ (-12).

For the writing part,

You could use the distributive property to simplify the equation and make it easier to solve for x.

Consider the following 8 numbers, where one labelled x

zvonat [6]

Step-by-step explanation:

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

we see that the visible 7 numbers have a range of 50-17 = 33.

that means that x has to make sure that the range really is 69.

so, we have indeed 2 choices : x can be the lowest value (with a difference of 69 to the highest value, 50), or x can be the highest value (with a difference of 69 to the lowest value, 17).

x as the lowest value :

x = 50 - 69 = -19

x as the highest value :

x = 17 + 69 = 86

12x+3=15x solve for x

malfutka [58]

$12x+3=15x\ \ \ \ |subtract\ 3\ from\ both\ sides\\\\12x=15x-3\ \ \ \ \ |subtract\ 15x\ from\ both\ sides\\\\-3x=-3\ \ \ \ \ |divide\ both\ sides\ by\ (-3)\\\\\boxed{x=1}\\\\check:\\\\L=12\cdot1+3=12+3=15\\R=15\cdot1=15\\\\L=R\ :)$
