Simplifying&#10;-1x + -1 = 221 + 2x&#10;&#10;Reorder the terms:&#10;-1 + -1x = 221 + 2x&#10;&#10;Solving&#10;-1 + -1x = 221 + 2x&#10;&#10;Solving for variable 'x'.&#10;&#10;Move all terms containing x to the left, all other terms to the right.&#10;&#10;Add '-2x' to each side of the equation.&#10;-1 + -1x + -2x = 221 + 2x + -2x&#10;&#10;Combine like terms: -1x + -2x = -3x&#10;-1 + -3x = 221 + 2x + -2x
Combine like terms: 2x + -2x = 0&#10;-1 + -3x = 221 + 0&#10;-1 + -3x = 221&#10;&#10;Add '1' to each side of the equation.&#10;-1 + 1 + -3x = 221 + 1&#10;&#10;Combine like terms: -1 + 1 = 0&#10;0 + -3x = 221 + 1&#10;-3x = 221 + 1&#10;&#10;Combine like terms: 221 + 1 = 222&#10;-3x = 222&#10;&#10;Divide each side by '-3'.&#10;x = -74&#10;&#10;Simplifying&#10;x = -74

Irina18 [472]

Answer: 8:9

Step-by-step explanation: Two find this answer, you need to see what will be the greatest number they can divide by (greatest common divider), it needs to be the same number for both 18 and 16.

Find two complex numbers that have a sum of i10 a different of -4and a product of -29​
lianna [129]
<h2>-2+5i and 2+5i</h2>

Step-by-step explanation:

   Let the complex numbers be a+ib\textrm{ and }c+id.

Given, sum is 10i, difference is -4 and product is -29.

(a+c)+i(b+d)=10i ⇒ a+c=0,b+d=10

(a-c)+i(b-d)=-4 ⇒ a-c=-4,b-d=0

a=-2,c=2,b=5,d=5

(a+ib)(c+id)=(-2+5i)(2+5i)=-4-25=-29

Hence, all three equations are consistent yielding the complex numbers -2+5i\textrm{ and }2+5i.
