= -
given
= 5 ( cross- multiply )
5(x + y) = x - y
5x + 5y = x - y ( subtract (x - y) from both sides )
4x + 6y = 0 ( subtract 6y from both sides )
4x = - 6y
= - = -
Answer:
I don't understand it there is supposed to be an (x) in the problem.
I got the answer 5-6=3.
Step-by-step explanation:
You do 1/2 times 10 and -12.
Or you divide 10 and -12 by 2.
5-6=3
This is the fundamental property of
i that you'll need to keep in mind when solving any problem with imaginary numbers (5i, 2i, 18i, etc.) or complex numbers (3+2i, 8-5i, etc). Squaring both sides of this definition, we also get that
Which we can use to solve this problem. We have:
Answer:
-1.85
