Add 6 to both sides and you get your final answer.
I think you should write the equation to find perimeter such as P = 2(L + W). So the expression is 2[2(x+y) + 3(x - y)]
Simplified as 2[(2x + 2y + 3x - 3y)]
2(5x - 1y) combined like terms
10x - 2y is the expression for the perimeter of the rectangle
2x+12=4x
Make two equations, and solve for x.
1. 2x+12= 4x 2. 2x+12= -4x subtract 2x from both sides
12=2x 12= -6x
6=x -2=x
plug in the x values to know if they are the solution for the eqaution.
2(6) +12= 4(6) 2(-2) +12= -4(-2)
12+12= 24 -4+12=8
24=24 8=8
The equation is true, it's all real numbers or infinite solutions.
