Answer:
n = 10
Step-by-step explanation:
Solve for n:
(3 n)/5 = 6
Multiply both sides of (3 n)/5 = 6 by 5/3:
(5×3 n)/(3×5) = 5/3×6
5/3×3/5 = (5×3)/(3×5):
(5×3)/(3×5) n = 5/3×6
5/3×6 = (5×6)/3:
(5×3 n)/(3×5) = (5×6)/3
(5×3 n)/(3×5) = (3×5)/(3×5)×n = n:
n = (5×6)/3
6/3 = (3×2)/3 = 2:
n = 5×2
5×2 = 10:
Answer: n = 10
Take second equation here,
2x + 9 = -12
2x = -12 - 9
2x = -21
Multiply by 2,
4x = -42
Now, substitute the vaue of 4x in 1st equation,
-42 - y = 2
-y = 2 + 42
y = -44
In short, Your Answer would be -44
Hope this helps!
Answer:
3000
Step-by-step explanation:
You can use photo math for This
F^-1(x)= (x+7)/2
it's the inverse so adding is subtracting and multiplication is divison
