1/2 and 1/3 are similar because 3/6 and 2/6 are similar. They are so close but not the same.
Use BODMAS or BIDMAS (Brackets, over Indices, Division, Multiplication, Addition, the Subtraction, this tells you which order to do things in)
As you cant do √10 in the brackets you do the indices, so (√10)³
Split this up to make it easier
(√10)³= √10 x √10 x √10 = 10√10
You the multiply this by 9
9 x 10√10 = 90√10
then multiply by 5
5 x 90√10 = 450√10 = 1423.024947 (using calculator)

Answer:
y = 5 -x
6x +3(5 -x) = 27
Step-by-step explanation:
The first equation is conveniently solved for either x or y. If we solve it for y, we get ...
y = 5 - x . . . . . . subtract x from both sides
This expression for y can be substituted into the second equation to give ...
6x +3(5 -x) = 27
These are your new system of equations.
Simplified, they are ...
_____
The second is a 2-step equation that gives the value of x, which can then be used in the first equation to find y.
3x = 12 . . . . subtract 15
x = 4 . . . . . . divide by 3
y = 5 -4 = 1 . . . . substitute into the first equation
The solution is (x, y) = (4, 1).
