2) Solve this system of linear equations by elimination. 2x+4y=-4

3x=-5y-3

*x=5,y=-2

*x=4,y=-3

*x=-5,y=2

*x=4,y=3

please answer step by step

x=4 and y=-3

Step-by-step explanation:

To use elimination to solve system of equations, you want to make sure the equations are first in standard form.

2x+4y=-4

3x+5y=-3

We want to make sure either the x or the y are equal so we can eliminate them. Let's eliminate x.

2x+4y=-4            [multiply equation by 3]

3x+5y=-3            [multiply equation by 2]

6x+12y=-12

6x+10y=-6

We can now subtract the equations.

2y=-6                  [divide both sides by 2]

y=-3

Now that we know y=-3, we can plug it into an equation to solve for x.

2x+4y=-4            [plug in y=-3]

2x+4(-3)=-4        [multiply]

2x-12=-4             [add both sides by 12]

2x=8                   [divide both sides by 2]

x=4

The final answer is x=4 and y=-3.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
