Which of the following gives a valid reason for using the given solution method to solve the system of equations shown? Equation I: 4x − 5y = 4 Equation II: 2x + 3y = 2

The solution of above equation is (1,1).

Given Equations  ......equation 1

......equation 2

On first instant we have in mind it is easy to eliminate from the equation for this we have to multiply equation 2 by 2 we get, ......equation 3

Now on subtracting equation 3 from 1 we get,

Or,

Putting the value of y =0 in equation 3, we get

Or,

Hence the solution of above equation is (1,1).

Eliminition method

Step-by-step explanation:

We have, two equations as follows :

4x − 5y = 4 ...(1)

2x + 3y = 2 ...(2)

Eliminition method is the good method to find the solution of above equations. It is very easy eliminate x. We can do it as follows :

Multiply equation (2) by 2 :

4x + 6y = 4 ...(3)

Now subtracting equation (3) from (1)

4x − 5y - (4x + 6y) = 4-4

-5y-6y = 0

y = 0

Now put y = 0 in equation (1)

4x − 5(0) = 4

x = 1

So, we get the value of x = 1 and y = 0 by using elimination method. It is one of the convenient method to solve.

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.
