Is (3,2) a solution to the system y -x =1 and -3x-2y=5 Yes, because (3, 2) is a solution to both equations.

No, because (3, 2) is a solution to only one equation.

Yes, because (3, 2) solution to one equation.

No, because (3, 2) is a solution to neither equation.

Step-by-step explanation:

Given point :-

Equations :-

=> y - x = 1

=> y = x + 1

=> -3x -2x -2 = 5

=> -5x = 7

=> x = -7/5

Therefore the point (3,2) is not a solution .

No, because (3, 2) is a solution to neither equation.

i think it might be a but you might want a second opinion

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
