Question

identify like terms in the following: (a)– xy2, – 4yx2, 8x2, 2xy2, 7y, – 11x2, – 100x, – 11yx, 20x2y,– 6x2, y, 2xy, 3x (b)10pq, 7p, 8q, – p2q2, – 7qp, – 100q, – 23, 12q2p2, – 5p2, 41, 2405p, 78qp,13p2q, qp2, 701p2

Answer 1

Answer:

3x – 7y = 7

11x + 5y = 87

5x + 4y = 43.

If so, find x and y.sove by elimination method

Answer 2

${\large{\sf{\green{Question}}}}$

${\large{\sf {Identify \: like \: terms \: in \: the \: following :-}}}$

$\sf \: (a) - xy^2, - 4yx^2, 8x^2, 2xy^2, 7y, - 11x^2, \\ \sf - 100x, - 11yx, 20x^2y, - 6x^2, y, 2xy, 3x$

$\sf \: (b) 10pq, 7p, 8q, - p^2q^2, - 7qp, - 100q, - 23, \\ \sf \: 12 q^2p ^2, - 5p^2, 41, \ 2405p, 78qp, 13p^2q, qp^2, 701p^2$

${\large{\sf{\blue {( 7y, y ),}}}}$

${\large{\sf{\pink {( - 100x, 3x )}}}}$

${\large{\sf{\green {( - 11yx, 2xy )}}}}$

${\large{\sf {(b) So \: like \: terms \: are :- }}}$

${\large{\sf{\red {( 10pq, 7qp, 78pq ),}}}}$
