Ihave three numbers. the biggest one is twice the middle one, and the biggest one plus the middle one is four times the smallest one. the smallest one plus the middle one is two less than the biggest one. what are the numbers?

Let

x------> the biggest number

y------> the middle number

z------> the smallest number

we know that

-------> equation

-------> equation

-------> equation

substitute equation in equation and equation

------> ------> equation

----> ------> equation

using a graph tool-----> to resolve the system of equations

see the attached figure

the solution is the point

Find the value of x

therefore

the answer is

the biggest number is

the the middle number is

the smallest number is

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
