Question
Choose the correct answer from the given four options :
If `[(x + 3, 4),(y - 4, x + y)] = [(5, 4),(3, 9)]` then the values of x and y are
Options
x = 2, y = 7
x = 7, y = 2
x = 3, y = 6
x = – 2, y = 7
Solution
`[(x + 3, 4),(y - 4, x + y)] = [(5, 4),(3, 9)]`
Comparing we get
x + 3 = 5
⇒ x = 5 – 3 = 2
and
y – 4 = 3
⇒ y = 3 + 4 = 7
x = 2, y = 7.
