Tricky Math question for geniuses!?

Question

x-y=733

x+y=-212

x=? y=?

Answer 1

x=-206.5

Answer 2

all of us understand that 2 numbers sum to 10 (upload to 10) and so as that they multiply to 5. permit's say the two numbers are: x and y consequently: x + y = 10 xy = 5 sparkling up utilising our gadget of equations strategies x = 10 - y substitute into 2d equation (10-y)y = 5 10y - y^2 = 5 0 = y^2 - 10y + 5 utilising the quadratic formulation, you will get: y = 5 +/- 2sqrt(5) properly then x may be the two: x = 10 - y x = 10 - (5 + 2sqrt(5)) or x = 10 - (5 - 2sqrt(5)) so our solutions are this: x = 5 - 2sqrt(5), y = 5 + 2sqrt(5) OR x = 5 + 2sqrt(5), y = 5 - 2sqrt(5) voila

Answer 3

It's not a tricky math question for geniuses. Those are two equations with two variables. You can eliminate one variable and solve for the other variable. You could then substitute that answer to solve for the other variable. Just add the two equations. The 'y's will cancel out and leave you with just the 'x' variable. It's easy.

Answer 4

x - y = 733

add y to each side to get

x = y + 733

Insert x into the x + y = -212 equation.

y + 733 + y = -212
2y + 733 = -212
2y = -945
y = -472.5

Put y into one of the equations, x - (-472.5) = 733

x + 472.5 = 733
x = 260.5

Answer 5

x = 733 + y

x = -212 - y

-212 - y = 733 + y

- 212 = 733 +2y
2y = -945
y = - 472.5 now solve for x

x - (-472.5) = 733
x = 733 - 472.5 = 260.5

Answer 6

x = 945/2
y = -521/2

Answer 7

x-y=733

x+y=-212
-________
2x = 521
x = 260.5

y= -472.5

Answer 8

x=2
y=2.5

Answer 9

x= 472.5
y= -260.5

Answer 10

y= -472.5
x= 260.5

Answer 11

x=472.5
y= -260.5
