Three numbers, x, y, z


The second of three numbers is one less than the first.
---
y=x-1


The third number is five less than the second.
---
z=y-5
z=x-1-5
z=x-6


If the first number is twice as large as the third,
---
x=2z
highlight_green%28x=2%28x-6%29%29, in one variable


x=2x-12
highlight_green%2812=x%29 and you can evaluate the other two numbers y and z.
