Question

X+Y=27 XY=70 linear equation

Answer 1

Answer:

x+y=27

By subsitution method

x=y-27

Putting in first eq.

xy=70

(y-27)y=70

y²-27y=70

y²-27y-70=0

Now u can solvethis by middle term split!!!!!!!..................

Answer 2

x+y=27

xy=72

y=72/x

x+72/x=27

x²+72=27x

x²-27x+72=0

x²-24x-3x+72=0

x(x-24)-3(x-24)=0

x=24,3

IF X=24,

xy=72

24y=72

y=3

IF X=3,

xy=72

3y=72

y=24

HOPE MY ANSWER IS CORRECT.
