A Rotation is a transformation of a figure by turning it around a given point.
Answer:
2x-8+3x+2=4x+10+3x-6
We move all terms to the left:
2x-8+3x+2-(4x+10+3x-6)=0
We add all the numbers together, and all the variables
2x+3x-(7x+4)-8+2=0
We add all the numbers together, and all the variables
5x-(7x+4)-6=0
We get rid of parentheses
5x-7x-4-6=0
We add all the numbers together, and all the variables
-2x-10=0
We move all terms containing x to the left, all other terms to the right
-2x=10
x=10/-2
x=-5
