That depends on what you mean by "6x 5", which could be 6x * 5, 6x + 5, 6x - 5, 6x / 5, 6x5, etc.
6X-5 = 31 (add 5 to both sides ) 6X = 36 ( divide both sides by 6 ) X = 6 ( check ) 6(6) -5 = 31 36-5 = 31 31 = 31
6!
If that's 6x - 5, x = 6
5-6x=5 -6x=0 X=undefined There is no answer its a trick question
6x-5 = 7, 6x = 7+5, 6x = 12, x = 2
5
y=(6x-5)/3
6x - 2x - 3 = 31 grouping the expressions with x: 6x - 2x = 31 + 3 simplifying: 4x = 34 solving for x x = 34/4 = 8.5
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
