Question

Xy-6,for x=4 and y=-2

Answer 1

(5, -1)

or

y = 4 − x

y = − 6 + x

Explanation:

Subtract x from both sides of the equation.

y = 4 − x

x − y = 6

Subtract x from both sides of the equation.

y = 4 − x

− y = 6 − x

Multiply each term in − y = 6 − x by −1

Answer 2

-14

Explanation:

replace x with 4 and y with -2

the equation is now (4-2) -6

multiple 4 times -2 you get -8 and then it is

-8 -6

the final answer is -14
