Could someone teach me how to do this question step by step i dont get it

Step-by-step explanation:

Written explanation:

You bring the y to the left side so it "matches" up with the bottom equation. Then you multiply -1 to the bottom or top (preferably the top) and add both equations. Then you solve like you normally would.

Visual explanation:

And then, you substitute y into one of the equations, find x, and wala! There might be more steps if you read the directions, but I am just explaining the actual part.

I hope that helps! If you have more questions (like Why did you do that? Where did you get that from?), don't hesitate to ask in the comments below. :)

how am i supposed to answer

step-by-step explanation:

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
