2x + y = 7 Put x=0 2×0 + y =7 0 +y = 7 Solution. (0, 7) Again put x=1 2×1+y =7 2 + y =7 Y= 7-2 Y=5 Solution. (1, 7) Similarly again put x= -1 2x + y= 7 2× (-1) + y =7 -2+y = 7 y=7+2 y=9 3rd solution.. (-1, 9) Finally put x=2 2x+y=7 2×2 + y=7 4 +y =7 y =7 -4 y=3 Solution.. (2, 3)

x + y = 8
xy = 15.

{tex}( x+y )^2 = x^2 + y^2 + 2xy{/tex}
{tex}x^2 + y^2 = ( x + y )^2 - 2xy{/tex}
{tex}= 8^2 - 2×15{/tex}
= 64 - 30
{tex}x^2 + y^2 = 34.{/tex}

Meet .B. Dattani 4 years, 1 month ago

Here, is your answer (x^m/x^n)^l * (x^n/x^l)^m * (x^l/x^m)^n =(x^ml/x^nl)*(x^nm/x^lm)*(x^ln/x^mn) =(x^ml-nl)*(x^nm-lm)*(x^ln-mn) =x^[(ml-nl)+(nm-lm)+(ln-mn)] =x^ml-nl+nm-lm+ln-mn Therefore, same variables with negetive and positive signs are cancelled (example:- ml and -ml are cancelled) = x Hope it helps you
