Question

X+y=8 You can find more Solutions by replacing x with other values and then solving for Y. For example, let X = 6. What is y? ... the solutions of x+y=8 x is 5 and y is 3

Answer 1

Explanation:

x + y = 8 ⇔ y = - x + 8

If x = 6 , then y = - 6 + 8 = 2

( 6, 2 )

If x = 0 , then y = 0 + 8 = 8

(0, 8)

If x = 8 , then y = - 8 + 8 = 0

(8, 0)
