Estimate the solution to the system of equations.

Mathematics
1 answer:
Nonamiya [84]4 years ago

Answer:

x= -7/5 y=8/5

Step-by-step explanation:

1. choose a variable to eliminate (i chose 6)

2. multiply the first equation by 2 and the second equation by 3

3. now you have

-6x+6y=18

6x-21y=-42

and the x's can now cancel out when you add the equations together

4. after adding the equations, you get

-15y=-24

5. solve for y (y= 8/5)

6. now plug in 8/5 for the y in one of the original equations to solve for x. (i chose the first one)

7. -3x+3(8/5)=9

-3x+24/5=9

-3x=21/5

x= -7/5

I need to know how to solve these simple interest word problems step by step.
LekaFEV [45]

Answer:

$236.38

3.20%

Step-by-step explanation:

Simple interest = PNR/100 where P = Principal = 13132/-

N = 8 months = 8/12 years and r = 2.7%

Hence simple interest = 13132 (8/12)(2.7/100)

= 236.376

= 236.38 dollars

-----------------------------------------------------

2) On the same notation, here PNR/100 = 8546(1)(R)/100=273.47

Solving

R = 273.47(100)/8546 = 3.19999

= 3.20% apprxy.


-------------------------------
