Question 422882
1) x + y + z = 44
2) y = 3x
3) z = x - 6
Substitute the value of y in 2) into equation 1):
x + 3x + z = 44 -> 4x + z = 44
Solve above equation for z in terms of x:
z = 44 - 4x
Substitute the above value for z into equation 3):
44 - 4x = x - 6 -> 5x = 50 -> x = 10
Therefore, from 2), y = 3*10 = 30
And finally, from 3) z = 10 - 6 -> z = 4
Ans: x=10,y=30,z=4
