When put in matrix form, the coefficients of
... 3x -2y = 7
... x + 4y = 2
look like
![\left[\begin{array}{cc}3&-2\\1&4\end{array}\right]](https://tex.z-dn.net/?f=%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D3%26-2%5C%5C1%264%5Cend%7Barray%7D%5Cright%5D%20%20)
The determinant is 3×4 - 1×(-2) = 14.

Answer:
solution:Here
Given,
Load=800 N
Load distance=2cm
Effort distance=260cm
Effort applied=?
We know that,
Load × Load distance = Effort × Effort distance
or, 800×2 = e × 260
or,1600 = 260e
or,e = 1600/260
Thus, e = <u>6.15</u><u> </u><u>N</u>
<u>Hence</u><u>,</u><u> </u><u>The</u><u> </u><u>effort</u><u> </u><u>applied</u><u> </u><u>=</u><u> </u><u>6.15</u><u> </u><u>N</u>
<u>Hope</u><u> </u><u>this</u><u> </u><u>answer</u><u> </u><u>helped</u><u> </u><u>you</u><u>.</u><u>.</u>

We are given with two equations 2x − 3y = −1 and <span>11x − 9y = −13. The problem says that when the first equation is multiplied by -3 which results to -6x + 9y = 3, the sum of the resulting equation and the second one is equal to 5x = -10. We verify this: -6x + 11x = 5x while -9 y and 9 y cancels out. 3+-13 equals -10. Hence the total is really 5x = - 10.</span>
