Please help work this equation
Flauer [41]

Hi!

<u>Given these two equations:</u>

x = y + 8

x + 4 = 2(y + 4)

We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:

(y+8)+4=2(y+4)

Combine like terms on both sides:

y+12=2y+8

Subtract y from both sides:

12=y+8

Subtract 8 from both sides:

y=4

Now, we can simply plug the y value in to the first equation, and solve for x:

x=4+8

Simplify:

x=12

<h3>Therefore, x is equal to 12 and y is equal to 4.</h3>

PLEASE HELP!! Serious answers only please!!
klemol [59]

Answer:

Step-by-step explanation:

Use the distributive property to get rid of the brackets.

9i + 2*7 + 2*3i        Use the multiplication property to simplify the imaginary terms

9i + 2*3i + 2*7        Do the same to the real term

9i + 6i + 14              Use the addition of like terms property

15i + 14                    And that's your answer.

You may not like my terminology, but you have to remember that every text teaches this differently.
