If this is just an expression, then all you have to do is combine like terms, or groups of numbers and variables that have the same variable.
When simplified, you get the equation
-12+ 16r or
-18+6+3r+13r=16r-12
Transformation involves changing the position of a shape.
The transformation from
to
is 90 degrees clockwise rotation
Using the coordinates of A and A', we have:


Notice that the x-coordinate is <em>negated </em>and then <em>swapped </em>with the y-coordinate.
i.e.

The transformation of a point from <em>(x,y) to (y,-x)</em> is a 90 degrees clockwise rotation.
Hence, the transformation from
to
is 90 degrees clockwise rotation

its b
Step-by-step explanation:
cuz to sides are the exact same then one side is bigger than the others :)
Substitute x into the second equation:
3(6y-11)-2y=-1
18y-33-2y=-1
16y=32
y=2
Then put the y value into the first equation to get x:
x=6(2)-11
x=1
There you go!
