Answer:
X = - 5
Step-by-step explanation:
The above word problem is mathematically interpreted thus:
-1X - 4X = -4 - 4X + 4 + 5
-5X = - 4 - 4X + 4 + 5
-5X = - 4 - 4X + 9
Collect like terms
-5X + 4X = - 4+ 9
-X = 5
i dont know
2n +10= 140
4n- 40= 80
2n= 3n - 20
it is the am progression or sum progression
under the condition of f(x)=x composite function is an identity one
