That's an equation where x = 5
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
13x + 15 = 11x - 5 2x = -20 x = -10
(3x-4)(x+5)
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
It is B, 0.
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
13x + 15 = 11x - 5 2x = -20 x = -10
(3x-4)(x+5)
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
-11x=22011x=-220x=-220/11=-20
It is B, 0.
20 = 400
4x + 8 + 7x + 12 = 11x + 20
X=16 (i failed Algebra so it's probably wrong :D )
If that's - 11x - 20, the answer is (4x + 5)(x - 4). If that's + 11x + 20, it gets ugly in a hurry.
20 plus 20 equals 4020 plus 20 = 40
