Question

Solve the equation. If there is no solution, write no solution. 10|n|-3=37.
A. n = 30 or n = –50
B. no solution
C. n = 4 or n = –4
D. n = 4

Answer 1

Answer:

C. n=4 or n=-4

Step-by-step explanation:

10lnl-3=37         original problem

      +3=+3         add 3 to both sides

10lnl=40            solve that portion

10lnl=40    

     10                 divide both sides by 10 to isolate the variable

lnl=4                  since n is an absolute value, it is the distance from zero making the solution 4 or -4.
