Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i

Answer:
The answer would be 24 balloons in total.
Step-by-step explanation:
Jorge bought 6 large balloons, which was 25% of ALL the balloons he bought.
Meaning that since 6 is 25% of the number 24, he bought 24 balloons in total.
PROOF:
25% * 24 = 6
24 / 6 = 4
6 * 4 = 24

The values of a and b equals 10
<u>4h + 7 = 4h - 3</u>
Subtract 4h from each side: 7 = -3
There is no value of ' h ' that can make this a true statement,
so the equation has no solution.
