(A) Given that the point $(a, a-2)$ lies on the graph of the equation $3x + 5y = 30$.This means that the coordinates of the point must satisfy the equation.Substitute $x = a$ and $y = a - 2$ into the equation:$3(a) + 5(a - 2) = 30$$3a + 5a - 10 = 30$$8a - 10 = 30$$8a = 30 + 10$$8a = 40$$a = 40 / 8$$a = 5$
