To solve the equation 2/5n - 7 = 8, you can follow these steps:
Step 1: Add 7 to both sides of the equation:
2/5n - 7 + 7 = 8 + 7
2/5n = 15
Step 2: To get rid of the fraction, multiply both sides of the equation by the reciprocal of the fraction, which is 5/2:
(2/5n)*(5/2) = 15*(5/2)
n = 75/2
Step 3: Simplify the right side of the equation:
n = 37.5
Therefore, the solution to the equation 2/5n - 7 = 8 is n = 37.5.
