Answer:
The answer is X - 10 = 0
If you click the image it will show you how to solve the equation. I hope this helps you :)
It is 6 because 3x3=9 then you do the same for 2 so 6/9
Let the numbers be x and y. Then xy = -30 and x+y = -3.
Solve xy = -30 for y: y = -30/x
subst. -30/x for y in x+y= -3: x - 30/x = -3
Multiply all 3 terms by x: x^2 - 30 = -3x, so x^2 + 3x - 10 = 0
Solve this quadratic equation for x. x: {-5, 2}
If x = -5, then x+y = -3 becomes -5 + y = -3, and y = 2.
You should check to determine whether x=2 is also correct. If it is, what is the corresponding y value?
X=-53x+378, if you need explanation used ask me.
