Solve the system of linear equations. separate the x- and y- values with a coma.
Katarina [22]
The Answer is x=7, y=6

Solve the following system:
{14 x - 4 y = 74 | (equation 1)
{7 x - 7 y = 7 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{14 x - 4 y = 74 | (equation 1)
{0 x - 5 y = -30 | (equation 2)
Divide equation 1 by 2:
{7 x - 2 y = 37 | (equation 1)
{0 x - 5 y = -30 | (equation 2)
Divide equation 2 by -5:
{7 x - 2 y = 37 | (equation 1)
{0 x+y = 6 | (equation 2)
Add 2 × (equation 2) to equation 1:
{7 x+0 y = 49 | (equation 1)
{0 x+y = 6 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 7 | (equation 1)
{0 x+y = 6 | (equation 2)
Collect results:
Answer:  {x = 7
                {y = 6

P{lease note the brackets are supposed to go over both equations but I haven'y been able to find a way to make it work, see attachment.

Which ratio is equivalent to 12: 54 ?<br><br> a. 3/13<br> b. 6/24<br> c.24/104<br> d.36/162
Brut [27]
It would be D.) 36/162

When you multiply 12 by 3, you get 36. You multiply the same number, 3, by 54 to get 162.

This means that the ratio is equivalent.

Which expression is equal to 21,340?
AfilCa [17]
To find the answer, move the decimal point over until you reach the final number. Move it to the right of that, and then count how many places you had to move over and write that as the exponent to 10. So the answer is A because you moved the decimal point 21640. <- here over 4 places, then you lose the zero.

Multiply and simplify x-1/ x^2+2x+1 x x^2-1/ x+1
notsponge [240]
\dfrac{x-1}{x^2+2x+1}\cdot\dfrac{x^2-1}{x+1}\\\\=\dfrac{(x-1)(x-1)(x+1)}{(x+1)^2(x+1)}\\\\=\dfrac{x^2-2x+1}{x^2+2x+1}
