Step 1: Simplify both sides of the equation.
−23(3x−4)+3x=56
(−23)(3x)+(−23)(−4)+3x=56(Distribute)
−69x+92+3x=56
(−69x+3x)+(92)=56(Combine Like Terms)
−66x+92=56
−66x+92=56
Step 2: Subtract 92 from both sides.
−66x+92−92=56−92
−66x=−36
Step 3: Divide both sides by -66.
−66x /-66= -36/-66
x= 6/11
Lets set up the relationship of the length to width:
l = 3w
Using this, we can make all the variables the same by substitution:
2l + 2w = perimeter
2l + 2w = 72
2(3w) + 2w = 72
6w + 2w = 72
8w = 72
w = 9
The width is 9, to the length must be 9*3, or 27.
Hope this helped!

x² - x - 12 ≠ 0
x² - 4x + 3x - 12 ≠ 0
x (x - 4) + 3 (x - 4) ≠ 0
(x + 3)(x - 4) ≠ 0
x ≠ -3 or x ≠ 4
