Substitute y=-x+6 x-2y=-6
Ksenya-84 [330]
<span><span>x-4x+12=6
-3x+12=6
-3x+12-12=6-12
-3x=-6
-3x/-3=-6/-3
x=2
Plug (2) in for x in L2 and solve for y:

y=2(2)-6
y=4-6
y=-2
The solution (x,y)=(2,-2)
Check in both equations by substituting (x,y)=(2,-2) and see if it equals out:
L1) (2)-2(-2)=6
2+4=6
6=6 L1 checks out.
L2) (-2)=2(2)-6
-2=4-6
-2=-2 L2 checks out also, so we can say with confidence that the solution is right.

Divide 6k2-15-5 by 3k
TEA [102]
Based on the question above, I believe that '6k2' would be (6k^2). So by this, I would continue to with the following expression as: 6k^2-15-5\div3k

Simplify: \frac{5}{3} \\ \\  ((6 * (k2)) -  15) - ( \frac{5}{3} *k) \\ \\  ((2*3k^2) -  15) -  \frac{5k}{3} \\ \\ \boxed{\boxed{6k^2 - 15 = \frac{6k^2-15}{1} =  \frac{(6k^2-15)*3}{3} }} \\ \\ (pull \ out \ like \ terms) \\ \\  6k^2 - 15  =   3 * (2k^2 - 5) \\ \\ Factoring:  2k^2 - 5

And by this, in order for us to fully understand that this would be true, the following would enable us to understand.

\Rightarrow  \left[\begin{array}{ccc}A+B) * (A-B) =\\&#10;         A2 - AB + BA - B2 =\\&#10;         A2 - AB + AB - B2 = \\&#10;         A2 - B2\end{array}\right] \Leftarrow

\boxed{\bf{ \frac{3*(2k^2-5)*3-(5k)}{3} =  \frac{18k^2-5k-45}{3} }}

Factoring : 18k^2 - 5k - 45 \\ \\   \left[\begin{array}{ccc}   -810    +    1    =    -809 \\&#10;      -405    +    2    =    -403 \\&#10;      -270    +    3    =    -267\\  -162    +    5    =    -157 \\&#10;      -135    +    6    =    -129 \\&#10;      -90    +    9    =    -81 &#10; &#10;  &#10;\end{array}\right]

(Your \ Answer) : \boxed{\boxed{\bf{ \frac{18k^2-5k-45}{3} }}}
