Solve this system of linear equations. separate the x - and y values with a comma. 6x+5y = 4 19x+2y = - 15

x = - 1, y = 2

Step-by-step explanation:

Given the 2 equations

6x + 5y = 4 → (1)

19x + 2y = - 15 → (2)

Multiplying (1) by 2 and (2) by - 5 and adding will eliminate the term in y

12x + 10y = 8 → (3)

- 95x - 10y = 75 → (4)

Add (3) and (4) term by term thus eliminating y

- 83x = 83 ( divide both sides by - 83 )

x = - 1

Substitute x = - 1 into either of the 2 equations and evaluate for y

Substituting into (1)

6(- 1) + 5y = 4

- 6 + 5y = 4 ( add 6 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2

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.

d is the answer
