4%n = 5
Simplify the equation
1/25n = 5
Multiply by 25
25 (1/25n) = (25) (5)
n = 125.
Input negative 18 into x and distribute. on both sides of the equal sign you should get 70=70
5y-10 and 2y-6 unless the two are together in which case are they being added or multiplied (the equations).
The new value would be $134.40; 1.12 times 120
