2t - 8 = 3t + 12
First you remove the outer numbers from one side of the equation. In this case, 12. But whatever you do to one side, you have to do the same for the other side.
2t - 8 - 12 = 3t
Then put all the terms with unknowns on one side.
-8 - 12 = 3t - 2t
We can simplify this into...
-20 = t
so...
t = -20.
hope that helps. :)
15x minus 8=minus 180 3x+8=24

12 + 5 equals...
(five cubed minus five) / (five plus five) equals 12
-9h - 6 + 12h + 40 = 22 ie 3h = 22 + 6 - 40 h= -12/3 = -4
15x minus 8=minus 180 3x+8=24
2(2*4-5)+6 = 12

12 + 5 equals...
(five cubed minus five) / (five plus five) equals 12
-9h - 6 + 12h + 40 = 22 ie 3h = 22 + 6 - 40 h= -12/3 = -4
I'll do ya one better - 12 plus 8 equals what?
a= -0.8
-0.5

If n + 7 = 12, then n = 12 - 7
