Question

Xy = 12
(x - 1)(y+ 2) = 15

Answer 1

To solve the given equations, we can use the substitution method and solve for the unknown variables x and y.

Step-by-step explanation:

In the given equations, we have:

1. Equation 1: xy = 12
2. Equation 2: (x - 1)(y + 2) = 15

To solve this, we can use a method called substitution. Let's substitute y in Equation 2 with its value from Equation 1.

From Equation 1, we have x = 12/y. Substitute this value of x in Equation 2:

(12/y - 1)(y + 2) = 15

Now we can simplify and solve this equation to find the values of x and y.
