One step equations- solve for "X" or find it. Please help

3x=-12
14x=280
x+6=-5
x+27=125
x-324=760
x-43=35
x/6=-24
x/13=214
26-x=47
-x/3=-998
I know, I always put 100 points, I just like giving extra points :) Merry almost Christmas also!!!

Since these are one-step equations we only have one step.

To solve, these single steps will include the following:

[1] addition (+)

[1] subtraction (-)

[2] division (/ or ÷)

[2] multiplication (* or x)

How do we answer these? We do the opposite of what is shown. If we have addition in 4 + x = 6, we will use subtraction to solve. The numbers one (1) and two (2) above show the "sets" of which we use.

[] 3x = -12

-> -4

We have multiplication so we will divide -12 by 3 for an answer of -4

[] 14x = 280

-> 20

We have multiplication so we will divide 280 by 14 for an answer of 20

[] x + 6 = -5

-> -11

We have addition so we will subtract 6 from -5 for an answer of -11

[] x + 27 = 125

-> 98

We have addition so we will subtract 27 from 125 for an answer of 98

[] x - 324 = 760

-> 1,084

We have subtraction so we will add 324 to 760 for an answer of 1,084

[] x - 43 = 35

-> 78

We have subtraction so we will add 43 to 35 for an answer of 78

[] x/6 = -24

-> -144

We have division so we will multiply 6 by -24 for an answer of -144

[] x/13=214

-> 2,782

We have division so we will multiply 13 by 214 for an answer of 2,782

[] 26 - x = 47

-> -21

We have subtraction so we will add x to both sides to reach the equation 26 = 47 + x

Then, we have addition so we will subtract 47 from 26 to get an answer of -21

[] -x/3=-998

-> 2,994

First, we will move the negative to the bottom of the fraction, which looks like this:
(-x)/(3) = (x)/(-3)

Then, we have division so we will multiply -3 by -998 for an answer of 2,994

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
