7n+12=1/2(14n+24) NEED ANSWER ASAP

Angelina_Jolie [31]

Answer:

n = all real numbers

Step-by-step explanation:

7n+12=1/2(14n+24)

multiply each side by 2

2(7n+12)=2*1/2(14n+24)

distribute

14n+24 = 14n + 24

subtract 14n from each side

14n-14n+24 = 14n-14n + 24

24=24

this is always true

n = all real numbers
