Question 299590
separate the number 42 into three parts so that the second number is 9 more than the first number which is the same as the third number,
-----------
Equations:
x + y + z = 42
y = x + 9
x = z
----
Substitute for y and for z; then solve for "x"
---
x + (x+9) + x = 42
3x = 31
x = 131/3
---
y = (131/3) + 9
---
z = 131/3
