Step-by-step explanation:

Answer 2

Answer:

Several equivalent equations are:

$2a-3\times 7=1\\ \\ 2a-21=1\\ \\ 2a=22\\ \\ a=11$

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:

$3\times ((2/3)a-7)=3\times (1/3)$

$2a-3\times 7=1\\ \\ 2a-21=1$

2. Add 21 to both sides:

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

3. Divide both sides by 2:

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