2013年6月23日 · So back to our problem, 3x = 27. All you need to do is get the x by itself, on one side of the equation. So the goal is to get that 3 away from the x. Suppose we took 3x and divided it by 3. Because of rule 1), we know that 3/3 = 1. So then 3x divided by 3 = 1x Because of rule 2) 1 * x = x, so 1x just becomes x. this is what we wanted, x by itself!

5ax+5a>/=2ax-3x-27+19x (3a-16)x >/=-5a-27. x >/= -(5a-27)/(3a-16) let a =16/3, then solution set for x is any real number. substitute that a value into the original equation/inequality to get. 5(16/3)x +5(16/3) >/= 2(16/3)x- 3x -27 +19x (48/3 -16)x >/= -27-80/3. 0>/= -53 2/3. 0 will always be greater than -53 2/3, regardless of the value of x
