Which of these strategies would eliminate a variable in the system of equations? { − x + 6 y = 8 7 x − y = − 2 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ −x+6y=8 7x−y=−2 Choose all answers that apply:

The required solution is  and .

Step-by-step explanation:

Given equations are

-x+6y = -2.......(1)

.......(2)

First we have to equate the coefficient of y or x. Here we equate the coefficient of y . So equation (2) multiply by 6.

Then the equation (2) becomes

........(3)

Since the signs of y are is opposite, so we adding (1) and (2).

Putting the value of equation (1)

The required solution is  and

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
