Question 154388This question is from textbook Advanced Mathematics
: (2x+y) + (3-5x)i = 1 -7i solve for x & y
I lumped the i's and the numbers together then squared everything to get
 29x^2+4xy-104x+y^2-2y=-101
The answer is x=2 & y=-3, but I can't get there.This question is from textbook Advanced Mathematics

Question 151967: 1. Using one of the laws of exponents, prove that any number raised to the power 0 is 1.
2. Using FOIL, simplify the expression "(3x + 2)(3x - 2)". Show that a particular factoring formula leads to the same answer.
3. If a fourth-degree polynomial is multiplied by a third-degree polynomial, what is the degree of the product? Explain your reasoning and provide examples to support your explanation.
4. Think of a condition under which the product of any two binomials is a binomial. You can support your answer with the help of one of the identities of factorization of polynomials.
5. (i) Is "12.5555…" a rational or irrational number? Explain.
(ii) Is "2.1273685…" a rational or irrational number? Explain.
(iii) Is "548/799" a rational or irrational number? Explain.
(iv) Simplify "(5 + 3i)(5 - 3i)". Is the result real, complex, or both? Explain.

Question 149761: Please can someone help me with this problem: For i= -1, 3i(2+5i)= x+6i,then x=?
This is how i tried to solve the problem: 3ix2=6i,and 3ix5i=15i,now i combine 6i+ 15i = x + 6i, I broke down the problem by adding 6i + 15i= 21i=x+6i, then i made the 21i negative on both sides:
21i = x + 6i
-21i -21i= -15, is this correct?
