-17-5(x+3)=3x plz help

katovenus [111]

Start by distributing the -5 into the x and 3
-17-5x-15=3x
add like terms
-5x-32=3x
add 32 to both sides
-5x=3x+32
subtract 3x from both
-8x=32
divide both by -8
x=-4

Step-by-step explanation:

The rotation matrix for 90° CCW is ...

$\left[\begin{array}{cc}0&-1\\1&0\end{array}\right]$

Then the rotated coordinates are ...

$\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right]\cdot\left[\begin{array}{ccc}0&-3&5\\0&1&2\end{array}\right]=\left[\begin{array}{ccc}0&-1&-2\\0&-3&5\end{array}\right]$
