(08.03)consider the following pair of equations:

y = −2x + 8
y = x − 1

explain how you will solve the pair of equations by substitution. show all the steps and write the solution in (x, y) form.

Step-by-step explanation:

y = -2x + 8

y = x - 1

solve by substitution

so y = -2x + 8so sub -2x + 8 in for y back in the OTHER equation

-2x + 8 = x - 1 add 2x to both sides

-2x + 2x + 8 = x + 2x - 1combine like terms

8 = 3x - 1add 1 to both sides

8 + 1 = 3x- 1 + 1combine like terms

9 = 3x now divide both sides by 3

9/3 = (3/3)xsimplify

3 = 1xwhich is the same as 3 = x

so now that we know x is 3, sub that back into either of ur original equations to find y

y = x - 1

y = 3 - 1

y = 2

lets check it(3,2)

y = -2x + 8                          y = x - 1

2 = -2(3) + 8                       2 = 3 - 1

2 = -6 + 8                          2 = 2 (correct)

2 = 2 (correct)

so ur solution is (3,2) <

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.

the answer is 1/4
