1a ) y = 25 / 21, x = - 22/21

1b ) NoSolution

Step-by-step explanation:

Problem 1a )

- x + 5y - 7 = 0, and 4y - 10 = 5x

Let us first convert each to standard form ⇒

- x + 5y = 7, and -5x + 4y = 10

Solving though elimination, we would multiply the first equation by -5 then adding to the second equation, solving for y through algebra ⇒

- 5 ( - x + 5y = 7 ), ⇒ 5x - 25y = - 35 ⇒ - 21y = - 25,

+ -5x + 4y = 10 + -5x + 4y = 10 y = 25 / 21

Now let us substitute this value of y into the first equation as to solve for x:

- x + 5 ( 25 / 21 ) = 7 ⇒ -x + 125 / 21 = 7 ⇒ -x = 22/21 ⇒ x = - 22/21

Problem 1b )

12x - 4y + 28 = 0, and 16y - 110 = 48x

Let us first convert each to standard form ⇒

12x - 4y = -28, and -48x + 16y = 110

Solving though elimination, we would multiply the first equation by 4 then adding to the second equation, solving for y through algebra ⇒

4 ( 12x - 4y = -28 ), ⇒ 48x - 16y = - 112 ⇒ 0 = -2,

+ - 48x + 16y = 110 + -48x + 16y = 110 NoSolution

Answer from: Quest

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.
