10/7 - 2/7
They both have common denominators so you can just subtract.
10-7 - 2/7= 9/2
9/2 is an improper fraction, so we need to convert it into a mixed number.
9/2 = 4 1/2
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
8y - 3 = 6y + 17 (add 3 to each side)
8y = 6y + 17 + 3
8y = 6y + 20 (subtract 6y from each side)
8y - 6y = 20
2y = 20 (divide 2 from each side)
2y/2 = 20/2
y = 10
The answer is y = 10
