Determine which method works, substitution or elimination? 4x^2+3y^2=42x^2-6y^2=-3
GarryVolchara [31]

Given:

\begin{gathered} 4x^2+3y^2=4 \\  \\ 2x^2-6y^2=-3 \end{gathered}

Find the method .

Sol:

\begin{gathered} 4x^2+3y^2=4..............(1) \\  \\ 2x^2-6y^2=-3.............(2) \end{gathered}

2eq(1) + eq(2) then,

8x^2+6y^2=8

Then apply the elimination method.

\begin{gathered} 8x^2+6y^2=8 \\ 2x^2-6y^2=-3 \\ --------- \\ 10x^2=5 \\  \\ x^2=\frac{5}{10} \\  \\ x=\sqrt{\frac{1}{2}} \end{gathered}

A total of $5000 is invested: part at 7% and the remainder at 12%. How much is invested at each rate if the annual interest is $
atroni [7]

The amount invested in the account that yields 7% interest is $4000.

The amount invested in the account that yields 12% interest is $1000.

<h3>What are the linear equations that represent the question?</h3>

a + b = 5000 equation 1

0.07a + 0.12b = 400 equation 2

Where:

a = amount invested in the account that yields 7% interest.

b =  amount invested in the account that yields 12% interest.

<h3>How much is invested at each rate?</h3>

Multiply equation 1 by 0.07

0.07a + 0.07b = 350 equation 3

Subtract equation 3 from equation 2

0.05b = 50

b = 50 / 0.05

b = 1000

Subtract 1000 from 5000: 5000 - 1000 = 4000
