$15. the mean a of two numbers, x and y, is given by a = $\frac{x + y}{2…$

Question

the mean a of two numbers, x and y, is given by a = $\frac{x + y}{2}$. solve for y.

Explanation:

Step1: Multiply both sides by 2

$2A = x + y$

Step2: Subtract x from both sides

$y = 2A - x$

Answer:

$y = 2A - x$
