What is x-2y=-1 and 2x+y=4 using elimination step by step

otez555 [7]

Answer:

x = 7/5 , y = 6/5

Step-by-step explanation using elimination:

Solve the following system:

{x - 2 y = -1 | (equation 1)

2 x + y = 4 | (equation 2)

Swap equation 1 with equation 2:

{2 x + y = 4 | (equation 1)

x - 2 y = -1 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + y = 4 | (equation 1)

0 x - (5 y)/2 = -3 | (equation 2)

Multiply equation 2 by -2:

{2 x + y = 4 | (equation 1)

0 x+5 y = 6 | (equation 2)

Divide equation 2 by 5:

{2 x + y = 4 | (equation 1)

0 x+y = 6/5 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 14/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 7/5 | (equation 1)

0 x+y = 6/5 | (equation 2)

Collect results:

Answer: {x = 7/5 , y = 6/5

Answer:

B) $\displaystyle x ≤ 0$

Step-by-step explanation:

2(x + 12) − 16 ≤ 8

$\displaystyle \frac{2(x + 12)}{2} ≤ \frac{24}{2} \\ \\ x + 12 ≤ 12 \\ \\ x ≤ 0$

Jessica has money in two savings accounts. One rate is 11% and the other is 14%. If she has $300 more in the 14% account and the

Gelneren [198K]

Answer:

$272 was invested in the savings account at 11%
$572 was invested in the savings account at 14%

Step-by-step explanation:

Let the amount in the savings account with 11% interest =x

She has $300 more in the 14% account.

Therefore amount saved at 14%=x+300

Simple Interest= Principal X (Rate/100) X Time

Since, the time is not given, we assume an annual interest.

Therefore, Time =1 Year

Total Interest = $110

Now, our total interest will be a sum of the interest earned at 11% and the interest earned at 14%.

$110=(x*0.11*1)+[(x+300)*0.14*1]\\110=0.11x+0.14x+42\\110=0.25x+42\\\text{Subtract 42 from both sides}\\110-42=0.25x+42-42\\68=0.25x\\\text{Divide both sides by 0.25 to obtain x}\\\frac{68}{0.25} =\frac{0.25x}{0.25} \\x=\$272$

Therefore:

$272 was invested in the savings account at 11%
$572 was invested in the savings account at 14%

Cheers!
