M y=6x-1 and -2x-3y=-2 using substitution

 x = 4 
y =23 

work:
 plug in the value of Y to -2x-3y=-2. -2x - 3(6x-1) = -2
 multiply 3 and the numbers in parenthesis. -2x -18x - 3 =-2
combine like terms (-2x -18x). -20x - 3 = -2
subtract 3 from both sides to isolate the variable. -20x = -5 
divide to isolate the variable (-20/-5) x = 4
-
now that we know the value of x, it'll be easy to find Y.
Plug it in to the first equation.
y=6(4)-1
y = 24 - 1
y = 23

so x = 4 
and y = 23 

hope this helps! :D

Dis the correct  answer

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
