Simplifying

Question

I got this

 

x= first number

y=secound number

v= third number

 

x+y+v=214

x=y+21

x+v=2v+25

 

I need to simplify these so I have three numbers

Answer 1

From the 2nd equation, y = x - 21

 

From the 3rd equation, v = x - 25

 

Now substitute those into the first equation.

 

x + y + v = 214

 

x +(x - 21) + (x - 25) = 214

 

Can you take it from here?
