The "answer" is the number that ' n ' must be
in order for the statement to be true.
15/(40-n) =1/5
Multiply each side of the equation by (40-n):
15 = (40-n)/5
Multiply each side by ( -5 ):
-75 = n-40
Add 40 to each side:
-35 = n

Solve by the substitution method 15x-20y equals -1 15y equals 2 plus 5x?
Given: 15x - 20y = -1 15y = 2 + 5x Then: 15x -20(2 + 5x)/15 = -1 ∴15x -40/15 - 100x/15 = -15/15 ∴225x/15 - 100x/15 = 40/15 - 15/15 ∴125x = 25 ∴x = 1/5 Check: 15(1/5) - 20(1/5) = -1 ∴3 - 4 = -1 ∴-1 = -1
