7(y+3)=5y+8<br> Is this <br> A.Solution<br> B.No Solution<br> C. Infinite Solution

faust18 [17]

First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

$a(b + c) = ab + ac$

Using this, we can multiply the 7 out to the $y$ and 3. This gives us:

$7y + 21 = 5y + 8$

Now, let's solve for $y$ :

$2y + 21 = 8$

$2y = -13$

$y = - \dfrac{13}{2}$

We can see that there is one solution for this equation because $y$ is equal to one definite value after solving. Thus, our answer is A, one solution.

How you do multiply complex numbers ? Example : (9 - 4i) (8 + 6i)

Andrew [12]

You multiply them just as you would multiply any normal polynomials, except there is a special rule. Since we know that i = √-1, the rule is that i² = -1. So, let's multiply:

$(9-4i)(8+6i) = 72+54i-32i-24i^2$
