55x + (-3) = 53x + 7can be written as55x - 3 = 53x + 7subtract 53x from both sides2x - 3 = 7add three to both sides2x = 10divided both sides by 2x = 5
53x or 5.3 by 10x or 530 by 0.1x
53x =15 : x = 53/15 = 3.5333 (4dp)
It's not something that can have a SOLUTION unless it EQUALS something. x + 53x = 54x. Does 54x = 1? Then x = 1/54. Does 54x = 108? Then x = 2. etc.
3x-1+10 = 53x + 9 = 53x = 5 - 93x = -4x = -4/3

-7+x=13x the -7=12x and x =-7/12
27878400 x 7 equals 195148800.
5-x equals 7 = -2
