Respuesta :

first one m = .0666666
second one i don't know
third one is .1

Answer:

The value of each variable is:

  • x= 1/15 or 0.066666667
  • y= 1.9333333
  • z= 0.1

Step-by-step explanation:

To identify each of the variables you just have to adequately clear the equation provided as I show you below:

  • First equation to identify x: 1=15x

Clear x by passing the number 15 that is multiplying on one side of the equation, to divide on the other side:

  • 1/15= x or x= 1/15

you can leave the value as fractional or decimal, in which case you just have to do the division.

Now you take the second equation:

  • 2=x+y.

You use this equation to clear the variable y, since you already identified the variable x with the previous equation, then first replace the values you already know:

  • 2= (1/15)+y

Remember that thanks to the commutative law of addition, write x + y is the same as writing y + x, so let's change that order so you don't get confused later:

  • 2= y+(1/15)

Since the value of x is adding, you can pass it to the other side to subtract and operate it:

  • 2-(1/15)= y
  • 1.9333333= y or y= 1.9333333

Now we bring the third equation to identify z:

  • 3= 30z

To identify the z, a process similar to that performed with the first equation is made, that is, to pass the number that is multiplying to the other side to divide:

  • 3/30= z
  • 0.1= z or z= 0.1
