if xy=7 and x-y=5, what are the values of x and y? please help!!!

Answer 1

x * y = 7
x - y = 5
One method:

express one variable in terms of the other variable and then solve the single variable expression.

If x - y = 5
then y = x - 5
substituting back into the first equation:
x * (x - 5)=7
Solve for x, then substitue the x value into either equation to solve for y.
You will probably need to use the quadratic formula to solve it.
