Answer:
(2n -3) + n = 102
2n - 3 + n = 102
3n - 3 = 102
3n = 105
n = 35 (the first number)
SO...
The other number is (2 x 35) - 3 =
70 - 3 = 67 (the second number)
The numbers are 35 and 67.
35 + 67 = 102 CHECK!
Answer:

Step-by-step explanation:
Given:

Required:
Solve for y (make y the subject of the formula)
SOLUTION:

Square both sides


Subtract both sides by x

Divide both sides by 2

Well 21 times 2 is 42 and 1/3 of 21 is 7 so 42+7 is 49. hope this is right
No, because negative base sometimes results in non-real or imaginary value.
