Question

जोड़िए: 14x + 10y – 12xy – 13, 18 – 7x – 10y + 8xy, 4xy

Sum

Solution

(14x + 10y - 12xy - 13) + (18 - 7x - 10y + 8yx) + 4xy

= 14x + 10y - 12xy - 13 + 18 - 7x - 10y + 8yx + 4xy

= 14x - 7x + 10y - 10y - 12xy + 8yx + 4xy - 13 + 18

= x (14 - 7) + y (10 - 10) + xy (-12 + 8 + 4) - 13 + 18

= 7x + 5
