2/3a - 2= 1/3
add 2 to both sides
2/3a= 2 1/3
change mixed fraction to improper
2/3a= 7/3
divide both sides by 2/3
a= 7/3 ÷ 2/3
to divide fraction, multiply by reciprocal (inverse)
a= 7/3 * 3/2
a= (7*3)/(3*2)
a= 21/6
reduce by 3
a= 7/2 OR 3 1/2

ANSWER: 7/2 OR 3 1/2

Hope this helps! :)

2/3a - 2 = 1/3
2/3a = 2 + 1/3
2/3a = 7/3
a = (7/3) / (2/3)
a = (7/3) * (3/2)
a = 21/6
a = 7/2 ---- that is the answer

Hope this helps!

The text of the Pythagorean Theorem The Pythagorean Theorem states: “The sum of the squares of the lengths of the two sides of the right triangle, which are the shortest sides in a right-angled triangle, is equal to the square of the length of the hypotenuse, which is the longest side of the triangle.”

And in symbols: Pythagorean theorem = ( A² + B² = C²)

where ;

● A, B: the two sides of a right triangle ABC.

● C: The hypotenuse of a right triangle is ABC, which is the longest side.

It should be noted that the inverse of the theory is also true; Since the triangle to which the Pythagorean theorem applies, namely: A² + B² = C², is necessarily a right-angled triangle.

<h3><u>In Vietnamese ( Bằng tiếng việt) ;</u></h3>

Nội dung của Định lý Pitago Định lý Pitago phát biểu: “Tổng bình phương độ dài hai cạnh của tam giác vuông, là cạnh ngắn nhất của tam giác vuông, bằng bình phương độ dài của cạnh huyền, là cạnh dài nhất của tam giác. "

Và trong các ký hiệu: Định lý Pitago = (A² + B² = C²)

ở đâu ;

● A, B: hai cạnh của tam giác vuông ABC.

● C: Cạnh huyền của tam giác vuông ABC là cạnh dài nhất.

Cần lưu ý rằng điều ngược lại của lý thuyết cũng đúng; Vì tam giác áp dụng định lý Pitago, cụ thể là: A² + B² = C², nhất thiết phải là tam giác vuông.

I hope I helped you^_^
