Answer:

Several equivalent equations are:


2a-3* 7=1\\ \\ 2a-21=1\\ \\ 2a=22\\ \\ a=11

Step-by-step explanation:

I will find several equivalent equations assuming the original equation is:


(2/3)a-7=1/3

1. Multiply both sides of the equation by 3:


3* ((2/3)a-7)=3* (1/3)


2a-3* 7=1\\ \\ 2a-21=1

2. Add 21 to both sides:


2a=1+21\\ \\ 2a=22

3. Divide both sides by 2:


a=22/2\\ \\ a=11
