Point (a, a) lies on the graph of the equation 3y = 2x -4 find the value of a

Substituting (x, y) with (a, a), since we have:

3a=2a-4, which means that 3a-2a=-4, that is a=-4.

So, the point is (-4, -4).

Remark: a point which lies in the graph of an equation is a solution of that equation. So x=a, y=a satisfies the equation  3y = 2x -4, which makes our substitution legitimate.

 (-4, -4).

The answer is: a = about 63.59ft2 for 15

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
