Question

Which of the following is the solution to the equation 4 over 5 times n = 20

N = 4
N= 12
N = 16
N = 25

Answer 1

(d) N = 25

Explanation:

The solution to a one-step linear equation can be found by performing the inverse of the operation that is performed on the variable.

(4/5)N = 20

(5/4)(4/5)N = (5/4)(20) . . . . . multiply by the inverse of the coefficient

N = 25 . . . . . simplify
